ITEM 1.  REPORTS TO STOCKHOLDERS.

The Report to Shareholders is attached herewith.


                      GAMCO INTERNATIONAL GROWTH FUND, INC.

                                  ANNUAL REPORT
                                DECEMBER 31, 2006









TO OUR SHAREHOLDERS,

      The Sarbanes-Oxley Act requires a Fund's principal executive and financial
officers  to  certify  the  entire   contents  of  the  semi-annual  and  annual
shareholder  reports in a filing with the Securities and Exchange  Commission on
Form N-CSR. This certification  would cover the portfolio  manager's  commentary
and  subjective  opinions  if they are  attached  to or a part of the  financial
statements. Many of these comments and opinions would be difficult or impossible
to certify.

      Because we do not want our portfolio  managers to eliminate their opinions
and/or  restrict their  commentary to historical  facts, we have separated their
commentary from the financial  statements and investment portfolio and have sent
it to  you  separately.  Both  the  commentary  and  the  financial  statements,
including  the  portfolio  of  investments,  will be available on our website at
www.gabelli.com/funds.

      Enclosed are the audited financial statements and the investment portfolio
as of  December  31,  2006 with a  description  of  factors  that  affected  the
performance during the past year.

PERFORMANCE DISCUSSION (UNAUDITED)

      For the twelve months ending  December 31, 2006 the net asset value of the
Fund (Class AAA)  appreciated  21.18% which compares with 23.95% for the average
International  Multi-Cap Growth Fund monitored by Lipper and 26.86% for the MSCI
EAFE Index.

      International  markets performed  strongly in 2006. Merger and acquisition
activity has been feverish and helped international  markets'  performance.  For
example, Europe surpassed the U.S. in 2006 with deal volume of $1.43 trillion, a
rise of 39% from  2005.  Gains  made  from  higher  stock  prices  were  further
augmented by the strength of most foreign currencies relative to the dollar. Ten
individual  stock  holdings of the Fund gained more than 30% in price during the
year. These included Xstrata,  Tokai Carbon Co., Canon Inc., Petrobras,  Saipem,
Swatch Group, Harmony Gold Mining Co., Bank of Ireland, William Demant Holdings,
and Ajinomoto Co.


                                                           Sincerely yours,

                                                           /s/ Bruce N. Alpert

(a) Returns  represent past  performance  and do not guarantee  future  results.
    Total returns and average annual returns  reflect changes in share price and
    reinvestment of distributions  and are net of expenses.  Investment  returns
    and the principal  value of an investment  will  fluctuate.  When shares are
    redeemed,  they  may be  worth  more  or  less  than  their  original  cost.
    Performance  returns  for  periods  less  than one year are not  annualized.
    Current  performance  may be  lower or  higher  than  the  performance  data
    presented.  Visit www.gabelli.com for performance information as of the most
    recent  month  end.  INVESTORS  SHOULD  CAREFULLY  CONSIDER  THE  INVESTMENT
    OBJECTIVES,  RISKS, CHARGES, AND EXPENSES OF THE FUND BEFORE INVESTING.  THE
    PROSPECTUS CONTAINS MORE INFORMATION ABOUT THIS AND OTHER MATTERS AND SHOULD
    BE READ CAREFULLY BEFORE INVESTING.
    Investing in foreign  securities  involves risks not  ordinarily  associated
    with  investments  in  domestic  issues,   including  currency  fluctuation,
    economic,  and political  risks.  The Class AAA Shares' net asset values are
    used to calculate performance for the periods prior to the issuance of Class
    A Shares,  Class B Shares,  and Class C Shares on July 25, 2001, January 17,
    2001, and December 17, 2000,  respectively.  The actual  performance for the
    Class  B  Shares  and  Class C  Shares  would  have  been  lower  due to the
    additional  expenses  associated  with these  classes of shares.  The Morgan
    Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE)
    Index (the "MSCI EAFE  Index") is an unmanaged  indicator  of  international
    stock market performance,  while the Lipper  International  Multi-Cap Growth
    Fund Average reflects the average  performance of mutual funds classified in
    this particular category.  Dividends are considered  reinvested.  You cannot
    invest directly in an index.
(b) Effective  February 15, 2007, Class AAA Shares are only offered to investors
    who are shareholders in one or more of the registered  funds  distributed by
    Gabelli & Company, Inc. prior to February 15, 2007.
(c) Includes the effect of the maximum  5.75% sales  charge at the  beginning of
    the period.
(d) Performance  results  include  the  deferred  sales  charges for the Class B
    Shares upon redemption at the end of the quarter, one year, three year, five
    year, ten year, and since  inception  periods of 5%, 5%, 3%, 2%, 0%, and 0%,
    respectively,  of the Fund's NAV at the time of purchase or sale,  whichever
    is lower. Class B Shares are not available for new purchases.
(e) Performance results include the deferred sales charge for the Class C Shares
    upon  redemption at the end of the quarter and one year periods of 1% of the
    Fund's NAV at the time of purchase or sale, whichever is lower.

GAMCO INTERNATIONAL GROWTH FUND, INC.
DISCLOSURE OF FUND EXPENSES (UNAUDITED)
For the Six Month Period from July 1, 2006 through December 31, 2006
                                                                   EXPENSE TABLE
- --------------------------------------------------------------------------------
We believe it is important for you to understand the impact of fees and expenses
regarding  your  investment.  All mutual  funds have  operating  expenses.  As a
shareholder  of a fund,  you  incur  ongoing  costs,  which  include  costs  for
portfolio  management,  administrative  services,  and shareholder reports (like
this one), among others.  Operating  expenses,  which are deducted from a fund's
gross income,  directly  reduce the investment  return of a fund.  When a fund's
expenses are expressed as a percentage of its average net assets, this figure is
known as the expense  ratio.  The  following  examples  are intended to help you
understand  the  ongoing  costs (in  dollars) of  investing  in your Fund and to
compare these costs with those of other mutual funds.  The examples are based on
an  investment  of $1,000 made at the beginning of the period shown and held for
the entire period.

The Expense Table below illustrates your Fund's costs in two ways:

ACTUAL FUND  RETURN:  This section  provides  information  about actual  account
values and actual expenses. You may use this section to help you to estimate the
actual  expenses that you paid over the period after any fee waivers and expense
reimbursements.  The "Ending  Account  Value"  shown is derived  from the Fund's
ACTUAL return during the past six months,  and the "Expenses Paid During Period"
shows the dollar  amount  that would have been paid by an  investor  who started
with $1,000 in the Fund. You may use this information,  together with the amount
you invested, to estimate the expenses that you paid over the period.

To do so, simply  divide your account  value by $1,000 (for  example,  an $8,600
account value  divided by $1,000 = 8.6),  then multiply the result by the number
given for your Fund under the heading  "Expenses Paid During Period" to estimate
the expenses you paid during this period.

HYPOTHETICAL 5% RETURN:  This section provides  information  about  hypothetical
account  values and  hypothetical  expenses  based on the Fund's actual  expense
ratio. It assumes a hypothetical  annualized return of 5% before expenses during
the period shown. In this case - because the hypothetical return used is NOT the
Fund's  actual  return - the  results  do not apply to your  investment  and you
cannot use the  hypothetical  account  value and expense to estimate  the actual
ending  account  balance or expenses  you paid for the period.  This  example is
useful in making  comparisons  of the ongoing costs of investing in the Fund and
other  funds.  To do so,  compare  this  5%  hypothetical  example  with  the 5%
hypothetical  examples that appear in shareholder reports of other funds.

Please note that the  expenses  shown in the table are meant to  highlight  your
ongoing  costs only and do not  reflect  any  transactional  costs such as sales
charges (loads),  redemption fees, or exchange fees, if any, which are described
in the Prospectus. If these costs were applied to your account, your costs would
be higher.  Therefore, the 5% hypothetical return is useful in comparing ongoing
costs only,  and will not help you determine the relative  total costs of owning
different funds. The "Annualized  Expense Ratio"  represents the actual expenses
for the last six  months  and may be  different  from the  expense  ratio in the
Financial Highlights which is for the year ended December 31, 2006.

  months multiplied by the average account value over the period,  multiplied by
  the number of days in the most recent fiscal half-year, then divided by 365.

GAMCO INTERNATIONAL GROWTH FUND, INC.
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
1. ORGANIZATION.  GAMCO International  Growth Fund, Inc. (the "Fund"),  formerly
Gabelli  International  Growth Fund,  Inc.,  was  organized on May 25, 1994 as a
Maryland  corporation.  The Fund is a diversified open-end management investment
company  registered  under the  Investment  Company Act of 1940, as amended (the
"1940 Act"). The Fund's primary objective is long-term capital appreciation. The
Fund commenced investment operations on June 30,1995.

2. SIGNIFICANT  ACCOUNTING POLICIES.  The preparation of financial statements in
accordance with United States ("U.S.") generally accepted accounting  principles
requires  management to make estimates and assumptions  that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those  estimates.  The  following  is a summary of  significant  accounting
policies followed by the Fund in the preparation of its financial statements.

SECURITY  VALUATION.  Portfolio  securities  listed or  traded  on a  nationally
recognized securities exchange or traded in the U.S. over-the-counter market for
which market quotations are readily available are valued at the last quoted sale
price or a market's  official  closing  price as of the close of business on the
day the  securities  are being  valued.  If there  were no sales  that day,  the
security is valued at the  average of the  closing  bid and asked  prices or, if
there were no asked  prices  quoted on that day,  then the security is valued at
the closing bid price on that day. If no bid or asked  prices are quoted on such
day,  the  security is valued at the most  recently  available  price or, if the
Board of  Directors  (the  "Board") so  determines,  by such other method as the
Board shall determine in good faith to reflect its fair market value.  Portfolio
securities  traded on more than one national  securities  exchange or market are
valued according to the broadest and most  representative  market, as determined
by Gabelli Funds, LLC (the "Adviser").

Portfolio  securities  primarily traded on a foreign market are generally valued
at the preceding  closing values of such securities on the relevant market,  but
may be fair valued  pursuant to  procedures  established  by the Board if market
conditions change  significantly after the close of the foreign market but prior
to the  close of  business  on the day the  securities  are being  valued.  Debt
instruments  with  remaining  maturities  of 60 days or less that are not credit
impaired are valued at amortized cost,  unless the Board  determines such amount
does not reflect the securities' fair value, in which case these securities will
be fair valued as determined by the Board.  Debt  instruments  having a maturity
greater  than 60 days for which  market  quotations  are readily  available  are
valued at the average of the latest bid and asked prices. If there were no asked
prices  quoted on such day,  the security is valued using the closing bid price.
Futures contracts are valued at the closing  settlement price of the exchange or
board of trade on which the applicable contract is traded.

Securities and assets for which market  quotations are not readily available are
fair  valued as  determined  by the  Board.  Fair  valuation  methodologies  and
procedures may include, but are not limited to: analysis and review of available
financial and non-financial  information  about the company;  comparisons to the
valuation and changes in valuation of similar securities, including a comparison
of foreign  securities to the equivalent U.S. dollar value ADR securities at the
close of the U.S.  exchange;  and evaluation of any other information that could
be indicative of the value of the security.

In September 2006, the Financial  Accounting Standards Board (the "FASB") issued
Statement  of  Financial   Accounting   Standards   ("SFAS")   157,  Fair  Value
Measurements,  which  clarifies  the  definition  of  fair  value  and  requires
companies  to expand  their  disclosure  about the use of fair  value to measure
assets and  liabilities  in interim  and annual  periods  subsequent  to initial
recognition.  Adoption of SFAS 157  requires  the use of the price that would be
received  to sell  an  asset  or paid to  transfer  a  liability  in an  orderly
transaction  between market  participants at the  measurement  date. SFAS 157 is
effective  for  financial  statements  issued for fiscal years  beginning  after
November 15, 2007, and interim  periods within those fiscal years. At this time,
management is in the process of reviewing the  requirements  of SFAS 157 against
its current valuation policies to determine future applicability.

GAMCO INTERNATIONAL GROWTH FUND, INC.
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
- --------------------------------------------------------------------------------
REPURCHASE  AGREEMENTS.  The Fund may  enter  into  repurchase  agreements  with
primary  government  securities dealers recognized by the Federal Reserve Board,
with  member  banks of the  Federal  Reserve  System,  or with other  brokers or
dealers that meet credit  guidelines  established by the Adviser and reviewed by
the Board.  Under the terms of a typical  repurchase  agreement,  the Fund takes
possession  of an  underlying  debt  obligation  subject to an obligation of the
seller to repurchase,  and the Fund to resell,  the obligation at an agreed-upon
price and time, thereby  determining the yield during the Fund's holding period.
The Fund will always receive and maintain  securities as collateral whose market
value, including accrued interest,  will be at least equal to 102% of the dollar
amount  invested by the Fund in each  agreement.  The Fund will make payment for
such  securities  only upon  physical  delivery  or upon  evidence of book entry
transfer of the collateral to the account of the  custodian.  To the extent that
any repurchase transaction exceeds one business day, the value of the collateral
is marked-to-market on a daily basis to maintain the adequacy of the collateral.
If the seller defaults and the value of the collateral declines or if bankruptcy
proceedings   are  commenced  with  respect  to  the  seller  of  the  security,
realization of the collateral by the Fund may be delayed or limited. At December
31, 2006, there were no open repurchase agreements.

FORWARD  FOREIGN  EXCHANGE  CONTRACTS.  The Fund may engage in  forward  foreign
exchange contracts for hedging a specific transaction with respect to either the
currency in which the  transaction is denominated or another  currency as deemed
appropriate by the Adviser. Forward foreign exchange contracts are valued at the
forward  rate and are  marked-to-market  daily.  The  change in market  value is
included in  unrealized  appreciation/depreciation  on  investments  and foreign
currency translations.  When the contract is closed, the Fund records a realized
gain or loss equal to the  difference  between the value of the  contract at the
time it was opened and the value at the time it was closed.

The use of forward foreign exchange contracts does not eliminate fluctuations in
the underlying prices of the Fund's portfolio securities,  but it does establish
a rate of exchange that can be achieved in the future.  Although forward foreign
exchange  contracts  limit the risk of loss due to a decline in the value of the
hedged currency, they also limit any potential gain that might result should the
value of the currency increase. In addition,  the Fund could be exposed to risks
if the  counterparties  to the  contracts  are unable to meet the terms of their
contracts.  At December 31, 2006,  there were no open forward  foreign  exchange
contracts.

FOREIGN CURRENCY TRANSLATIONS.  The books and records of the Fund are maintained
in  U.S.  dollars.  Foreign  currencies,   investments,  and  other  assets  and
liabilities  are translated  into U.S.  dollars at the current  exchange  rates.
Purchases  and  sales  of  investment  securities,   income,  and  expenses  are
translated  at the exchange  rate  prevailing  on the  respective  dates of such
transactions.  Unrealized  gains and losses that result from  changes in foreign
exchange rates and/or changes in market prices of securities  have been included
in unrealized  appreciation/depreciation  on  investments  and foreign  currency
translations.  Net realized  foreign  currency  gains and losses  resulting from
changes in exchange  rates include  foreign  currency  gains and losses  between
trade date and settlement date on investment  securities  transactions,  foreign
currency  transactions,  and the difference  between the amounts of interest and
dividends  recorded on the books of the Fund and the amounts actually  received.
The  portion of foreign  currency  gains and losses  related to  fluctuation  in
exchange rates between the initial trade date and subsequent  sale trade date is
included in realized  gain/(loss) on investments.

FOREIGN  SECURITIES.  The Fund  may  directly  purchase  securities  of  foreign
issuers.  Investing in securities of foreign issuers  involves special risks not
typically  associated  with investing in securities of U.S.  issuers.  The risks
include  possible  revaluation of currencies,  the ability to repatriate  funds,
less complete financial information about companies, and possible future adverse
political  and  economic  developments.  Moreover,  securities  of many  foreign
issuers and their markets may be less liquid and their prices more volatile than
those of securities of comparable U.S. issuers.

FOREIGN  TAXES.  The Fund may be subject to  foreign  taxes on income,  gains on
investments,  or currency  repatriation,  a portion of which may be recoverable.
The Fund will accrue such taxes and  recoveries  as  applicable,  based upon its
current interpretation of tax rules and regulations that exist in the markets in
which it invests.

SECURITIES  TRANSACTIONS  AND INVESTMENT  INCOME.  Securities  transactions  are
accounted  for on the  trade  date  with  realized  gain or loss on  investments
determined  by using the  identified  cost method.  Interest  income  (including
amortization  of premium and  accretion  of discount) is recorded on the accrual
basis.  Premiums  and  discounts  on debt  securities  are  amortized  using the
effective  yield  to  maturity  method.  Dividend  income  is  recorded  on  the
ex-dividend date except for certain  dividends which are recorded as soon as the
Fund  is  informed  of the  dividend.

DETERMINATION   OF  NET  ASSET  VALUE  AND  CALCULATION  OF  EXPENSES.   Certain
administrative  expenses are common to, and allocated among,  various affiliated
funds.  Such allocations are made on the basis of each Fund's average net assets
or other criteria  directly  affecting the expenses as determined by the Adviser
pursuant to procedures established by the Board.

In calculating  the net asset value ("NAV") per share of each class,  investment
income, realized and unrealized gains and losses,  redemption fees, and expenses
other than class specific expenses,  are allocated daily to each class of shares
based upon the  proportion  of net assets of each class at the beginning of each
day. Distribution expenses are borne solely by the class incurring the expense.

CUSTODIAN FEE CREDITS AND INTEREST EXPENSE. When cash balances are maintained in
the  custody  account,  the Fund  receives  credits  which  are  used to  offset
custodian  fees.  The gross  expenses  paid under the  custody  arrangement  are
included in custodian fees in the Statement of Operations with the corresponding
expense offset, if any, shown as "custodian fee credits". When cash balances are
overdrawn, the Fund is charged an overdraft fee equal to 2.00% above the Federal
Funds rate on  outstanding  balances.  This  amount,  if any,  would be shown as
"interest expense" in the Statement of Operations.

DISTRIBUTIONS TO SHAREHOLDERS. Distributions to shareholders are recorded on the
ex-dividend date.  Distributions to shareholders are based on income and capital
gains as determined in accordance with Federal income tax regulations, which may
differ from income and capital gains as determined under U.S. generally accepted
accounting  principles.   These  differences  are  primarily  due  to  differing
treatments  of income and gains on various  investment  securities  and  foreign
currency  transactions  held by the  Fund,  timing  differences,  and  differing
characterizations  of  distributions  made by the Fund.  Distributions  from net
investment  income include net realized gains on foreign currency  transactions.
These book/tax  differences are either temporary or permanent in nature.  To the
extent these differences are permanent,  adjustments are made to the appropriate
capital   accounts   in  the   period   when  the   differences   arise.   These
reclassifications  have no impact on the NAV of the Fund.  For the  fiscal  year
ended December 31, 2006, reclassifications were made to increase accumulated net
investment  income by $3,958 and to increase  accumulated  net realized  loss on
investments and foreign  currency  transactions by $3,958.

The tax character of  distributions  paid during the fiscal years ended December
31, 2006 and December 31, 2005 was as follows:

PROVISION  FOR  INCOME  TAXES.  The Fund  intends  to  continue  to qualify as a
regulated  investment company under Subchapter M of the Internal Revenue Code of
1986, as amended (the  "Code").  It is the policy of the Fund to comply with the
requirements of the Code applicable to regulated investment companies and to

distribute  substantially  all of its net investment  company taxable income and
net capital gains. Therefore, no provision for Federal income taxes is required.

At December 31, 2006, the difference between book basis and tax basis unrealized
appreciation was  primarily due  to deferral  of  losses from wash sales for tax
purposes.

As of December 31, 2006, the components of  accumulated  earnings/(losses)  on a
tax basis were as follows:

  Undistributed ordinary income ............................. $        81
  Capital loss carryforward                                    (5,278,666)
  Net unrealized appreciation on investments and
    foreign receivables and payables ........................  22,037,983

                                                              ===========

At December 31, 2006,  the Fund had net capital loss  carryforwards  for Federal
income tax purposes of $5,278,666, which are available to reduce future required
distributions  of net  capital  gains to  shareholders.  $2,552,760  of the loss
carryforward is available through 2010 and $2,725,906 is available through 2011.
For the fiscal year ended  December 31, 2006, the Fund utilized net capital loss
carryforwards of $5,372,933.

The following  summarizes the tax cost of investments and the related unrealized
appreciation/(depreciation) at December 31, 2006:

In July 2006, the FASB issued Interpretation No. 48, "Accounting for Uncertainty
in  Income  Taxes,   an   Interpretation   of  FASB  Statement  No.  109"  ("the
Interpretation").  The  Interpretation  establishes for all entities,  including
pass-through  entities  such as the Fund,  a  minimum  threshold  for  financial
statement  recognition  of the benefit of positions  taken in filing tax returns
(including  whether  an entity is  taxable in a  particular  jurisdiction),  and
requires certain expanded tax disclosures.  The Interpretation is required to be
implemented  for a  calendar-year  open-end fund no later than its June 29, 2007
NAV, and is to be applied to all open tax years as of the date of effectiveness.
Management has begun to evaluate the  application of the  Interpretation  to the
Fund, and is not in a position at this time to estimate the  significance of its
impact, if any, on the Fund's financial statements.

3. INVESTMENT  ADVISORY AGREEMENT AND OTHER  TRANSACTIONS.  The Fund has entered
into an  investment  advisory  agreement  (the  "Advisory  Agreement")  with the
Adviser which provides that the Fund will pay the Adviser a fee,  computed daily
and paid monthly,  at the annual rate of 1.00% of the value of its average daily
net assets.  In accordance with the Advisory  Agreement,  the Adviser provides a
continuous   investment   program  for  the  Fund's   portfolio,   oversees  the
administration  of all aspects of the Fund's business and affairs,  and pays the
compensation  of all  Officers  and  Directors  of the Fund  who are  affiliated
persons of the Adviser.

If total  net  assets  of the Fund are below  $100  million,  the Fund pays each
Director that is not considered to be an affiliated person an annual retainer of
$1,000 plus $250 for each Board meeting attended and they are reimbursed for any
out of pocket expenses  incurred in attending  meetings.  If total net assets of
the Fund are in excess of $100 million,  the Fund pays each Independent Director
an annual retainer of $3,000 plus $500 for each Board meeting  attended and they
are reimbursed for any out of pocket  expenses  incurred in attending  meetings.
All Board committee members receive $500 per meeting attended. Directors who are
directors  or  employees  of the  Adviser or an  affiliated  company  receive no
compensation or expense reimbursement from the Fund.

4.  DISTRIBUTION  PLAN.  The Fund's Board has adopted a  distribution  plan (the
"Plan")  for each class of shares  pursuant  to Rule  12b-1  under the 1940 Act.
Gabelli & Company,  Inc.  ("Gabelli &  Company"),  an  affiliate of the Adviser,
serves as  distributor  of the Fund.  Under the Class AAA, Class A, Class B, and
Class C Share Plans,

                                       12


GAMCO INTERNATIONAL GROWTH FUND, INC.
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
- --------------------------------------------------------------------------------
payments are  authorized  to Gabelli & Company at annual rates of 0.25%,  0.25%,
1.00%,  and  1.00%,  respectively,  of the  average  daily  net  assets of those
classes, the annual limitations under each Plan. Such payments are accrued daily
and paid monthly.

5. PORTFOLIO SECURITIES. Purchases and proceeds from the sales of securities for
the  fiscal  year ended  December  31,  2006,  other  than  short-term  and U.S.
Government securities, aggregated $11,745,586 and $17,437,904, respectively.

6. TRANSACTIONS WITH AFFILIATES. During the fiscal year ended December 31, 2006,
Gabelli  &  Company  informed  the Fund that it  received  $269  from  investors
representing  commissions  (sales  charges and  underwriting  fees) on sales and
redemptions of Fund shares.

The cost of calculating  the Fund's NAV per share is a Fund expense  pursuant to
the Advisory Agreement between the Fund and the Adviser.  During the fiscal year
ended  December  31,  2006,  the Fund paid or accrued  $45,000 to the Adviser in
connection with the cost of computing the Fund's NAV.

7. LINE OF CREDIT.  The Fund has access to an unsecured  line of credit of up to
$25,000,000  from the  custodian for temporary  borrowing  purposes.  Borrowings
under this  arrangement  bear  interest at 0.75% above the Federal Funds rate on
outstanding balances.  This amount, if any, would be shown as "interest expense"
in the Statement of Operations.  At December 31, 2006,  there were no borrowings
outstanding  from the line of credit.

The  average  daily  amount of  borrowings  outstanding  from the line of credit
within the fiscal year ended  December  31, 2006 was  $179,995,  with a weighted
average  interest rate of 6.03%.  The maximum amount borrowed at any time during
the fiscal year ended December 31, 2006 was $3,943,000.

8. CAPITAL STOCK TRANSACTIONS.  The Fund currently offers four classes of shares
- - Class  AAA  Shares,  Class A  Shares,  Class B  Shares,  and  Class C  Shares.
Effective  February 15, 2007, Class AAA Shares are offered only to investors who
are  shareholders  prior  to that  date in one or more of the  registered  funds
distributed  by  Gabelli  &  Company.  Class AAA  Shares  are  offered  to these
investors only through selected broker/dealers,  or the transfer agent without a
sales charge.  Class A Shares are subject to a maximum front-end sales charge of
5.75%. Class B Shares are subject to a contingent deferred sales charge ("CDSC")
upon redemption within six years of purchase and automatically  convert to Class
A Shares  approximately eight years after the original purchase.  The applicable
CDSC is equal to a  declining  percentage  of the lesser of the NAV per share at
the date of the  original  purchase or at the date of  redemption,  based on the
length of time  held.  Class C Shares  are  subject to a 1.00% CDSC for one year
after  purchase.  Class B Shares are available only through  exchange of Class B
Shares of other funds  distributed by Gabelli & Company.  The Board has approved
Class I Shares which have not been offered publicly.

The Fund imposes a redemption fee of 2.00% on Class AAA Shares,  Class A Shares,
Class B Shares,  and Class C Shares that are  redeemed or exchanged on or before
the seventh day after the date of a purchase.  (Prior to June 15, 2005, the Fund
imposed a redemption  fee on shares that were redeemed or exchanged on or before
the sixtieth day after the date of a purchase.)  The  redemption fee is deducted
from  the  proceeds  otherwise  payable  to the  redeeming  shareholders  and is
retained by the Fund. The redemption fees retained by the Fund during the fiscal
years ended  December 31, 2006 and December 31, 2005 amounted to $81 and $2,588,
respectively.

The redemption fee does not apply to shares purchased  through programs that the
Adviser  determined to have  appropriate  short-term  trading policies in place.
Additionally,  certain recordkeepers for qualified and non-qualified  retirement
plans that could not collect the redemption fee at the participant  level due to
systems limitations have received an extension to implement such systems.

9.  INDEMNIFICATIONS.  The Fund enters into  contracts that contain a variety of
indemnifications.  The Fund's  maximum  exposure  under  these  arrangements  is
unknown.  However, the Fund has not had prior claims or losses pursuant to these
contracts and expects the risk of loss to be remote.

10. OTHER MATTERS. The Adviser  and/or  affiliates  received  subpoenas from the
Attorney General of the State of New York and the SEC requesting  information on
mutual fund share  trading  practices  involving  certain  funds  managed by the
Adviser.  GAMCO  Investors,   Inc.  ("GAMCO"),  the  Adviser's  parent  company,
responded to these  requests for documents and  testimony.  In June 2006,  GAMCO
began discussions with the SEC regarding a possible resolution of their inquiry.
In February  2007,  the Adviser made an offer of  settlement to the staff of the
SEC for  communication  to the Commission for its  consideration to resolve this
matter.  This offer of settlement is subject to agreement regarding the specific
language of the SEC's administrative order and other settlement documents.  On a
separate matter, in September 2005, the Adviser was informed by the staff of the
SEC that the staff may recommend to the Commission that an administrative remedy
and a monetary penalty be sought from the Adviser in connection with the actions
of two of seven  closed-end  funds  managed by the  Adviser  relating to Section
19(a)  and Rule  19a-1 of the 1940  Act.  These  provisions  require  registered
investment  companies  to provide  written  statements  to  shareholders  when a
dividend is made from a source other than net investment  income.  While the two
closed-end funds sent annual statements and provided other materials  containing
this information, the funds did not send written statements to shareholders with
each  distribution in 2002 and 2003. The Adviser  believes that all of the funds
are now in  compliance.  The Adviser  believes  that these matters would have no
effect on the Fund or any material  adverse effect on the Adviser or its ability
to manage the Fund.

GAMCO INTERNATIONAL GROWTH FUND, INC.
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------
To the Shareholders and Board of Directors of
GAMCO International Growth Fund, Inc.

We have audited the  accompanying  statement of assets and  liabilities of GAMCO
International  Growth Fund, Inc. (the "Fund")  (formerly  Gabelli  International
Growth Fund,  Inc.),  including the schedule of investments,  as of December 31,
2006,  and the related  statement  of  operations  for the year then ended,  the
statements of changes in net assets for each of the two years in the period then
ended,  and the  financial  highlights  for each of the five years in the period
then  ended.  These  financial  statements  and  financial  highlights  are  the
responsibility  of the Fund's  management.  Our  responsibility is to express an
opinion on these  financial  statements  and financial  highlights  based on our
audits.

We conducted our audits in accordance  with the standards of the Public  Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material  misstatement.  We were
not engaged to perform an audit of the Fund's  internal  control over  financial
reporting.  Our audits included consideration of internal control over financial
reporting as a basis for designing audit  procedures that are appropriate in the
circumstances,  but  not  for  the  purpose  of  expressing  an  opinion  on the
effectiveness  of  the  Fund's  internal   control  over  financial   reporting.
Accordingly,  we express no such opinion. An audit also includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements and financial  highlights,  assessing the accounting  principles used
and  significant  estimates  made by  management,  and  evaluating  the  overall
financial  statement  presentation.  Our  procedures  included  confirmation  of
securities  owned as of December 31,  2006,  by  correspondence  with the Fund's
custodian.  We  believe  that our  audits  provide  a  reasonable  basis for our
opinion.

In our opinion,  the financial  statements and financial  highlights referred to
above present fairly, in all material respects,  the financial position of GAMCO
International  Growth  Fund,  Inc.  at  December  31,  2006,  the results of its
operations  for the year then  ended,  the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the five years in the period  then  ended,  in  conformity  with U.S.  generally
accepted accounting principles.

                                                           /s/ Ernst & Young LLP

ADDITIONAL FUND INFORMATION (CONTINUED) (UNAUDITED)
================================================================================

                   2006 TAX NOTICE TO SHAREHOLDERS (Unaudited)

    For the year ended  December 31,  2006,  the Fund paid to  shareholders,  on
    December 27, 2006, an ordinary income dividend  (comprised of net investment
    income) totaling $0.428, $0.433, $0.272, and $0.385 per share for Class AAA,
    Class A, Class B, and Class C, respectively. For the year ended December 31,
    2006, 100% of the distribution qualifies for the dividend received deduction
    available to corporations, and 100% of the ordinary income distributions was
    qualified  dividend  income.  Also for the year ended December 31, 2006, the
    Fund passed  through  foreign tax credits of $0.0393 per share to Class AAA,
    Class A, Class B, and Class C  shareholders.  The foreign  source income and
    tax  credits  by  country  are   presented   in  the  table   below.   Visit
    www.gabelli.com  for more  information  about 2006 foreign source income and
    foreign taxes paid.

    U.S. GOVERNMENT INCOME
    The  percentage  of the  ordinary  income  dividend  paid by the Fund during
    fiscal year 2006 which was derived from U.S. Treasury securities  was 0.81%.
    Such income is exempt from state and local tax in all states.  However, many
    states,  including  New York and  California,  allow a tax  exemption  for a
    portion of the income earned only if a mutual fund has invested at least 50%
    of its assets at the end of each  quarter of the Fund's  fiscal year in U.S.
    Government securities. The GAMCO International Growth Fund did not meet this
    strict requirement in 2006. Due to the diversity in state and local tax law,
    it is  recommended  that you  consult  your  personal  tax advisor as to the
    applicability of the information provided to your specific situation.

         services are promptly  brought to the  attention of the  Committee  and

         registrant was $100,600 for 2005 and $73,050 for 2006.

     (h) The  registrant's  audit  committee  of  the  board  of  directors  has

         sub-adviser  whose  role  is  primarily  portfolio  management  and  is
         subcontracted with or overseen by another investment adviser),  and any
