ITEM 1. REPORTS TO STOCKHOLDERS.

The Report to Shareholders is attached herewith.


                      GAMCO INTERNATIONAL GROWTH FUND, INC.

                                  ANNUAL REPORT
                               DECEMBER 31, 2005





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,  2005 with a  description  of  factors  that  affected  the
performance during the past year.

PERFORMANCE DISCUSSION

      For 2005, the GAMCO International Growth Fund returned 10.5% compared with
a rise of 14.0% for the MSCI EAFE Index and 15.4% for the average  International
Multi-Cap Growth Fund monitored by Lipper.

      The  Japanese  equity  market  was  rerated  in  2005.  Japan  was the top
performer  among  leading  non-U.S.  equity  markets.  Again  smaller  companies
outperformed with the TOPIX second section index rallying 41.9% in 2005. Most of
the  Japanese  holdings  in the Fund in 2005 had a total  return  of over 25% in
2005, among them Nikko Cordial Corp., Secom Co. Ltd.,  Hisamitsu  Pharmaceutical
Co. Inc., Keyence Corp., Tokai Carbon Co. Ltd., and Matsumotokiyoshi Co. Ltd.

      Clearly,  the European story does not revolve around growth.  Rather it is
based on corporate self help.  Corporate  managers are acutely aware of the need
to create  shareholder  value,  as Europe has become the center of global merger
and acquisition activity in 2005. Two investment bank holdings, which facilitate
merger and acquisition  deals, UBS AG and Credit Suisse Group, were up 40.2% and
31.3% in 2005, respectively.

      The Fund's  metal  mining  holdings  had an  outstanding  2005,  including
Harmony Gold Mining Co. Ltd. (+65.8%),  Xstrata plc (+45.6%), and Newmont Mining
Corp.  (+20.2%).  Another top performing sector in our portfolio during the last
year was energy and  utilities.  Among the best  performing  energy and  utility
companies in 2005 were Petrobras Brasiliero SA (+79.2%),  Total SA (+32.1%), and
Eni SpA  (+27.2%).  Pharmaceuticals  and  healthcare  holdings  were also on the
upswing in the past  twelve  months  with  Astrazeneca  plc,  Roche  Holding AG,
Hisamitsu Pharmaceuticals Co. Inc. and William Demant Holding A/S each recording
gains of more than 30%.

      The  dollar  benefited  during  the past year  from  strong  inflows  from
overseas investors, which had a negative impact on the dollar denominated return
of the Fund.

      Entertainment  and media companies  underperformed  the market in 2005. Of
the portfolio  holdings  Publishing & Broadcasting Ltd. (-5.8%) and Mediaset SpA
(-3.9%)  dragged  returns.  Other Fund holdings that  disappointed  in 2005 were
Ajinomoto  Co.  Inc.  (-0.7%),  Synthes  Inc.  (unchanged),  Smith & Nephew  plc
(+0.4%), and Cheung Kong (Holdings) Ltd. (+2.7%).

                                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 DIVIDENDS 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

     RISKS,  CHARGES,  AND EXPENSES OF THE FUND CAREFULLY 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

GAMCO INTERNATIONAL GROWTH FUND, INC.
DISCLOSURE OF FUND EXPENSES (UNAUDITED)
For the Six Month Period from July 1, 2005 through December 31, 2005
                                                                   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, 2005.

*  Expenses are equal to the Fund's  annualized  expense  ratio for the last six
   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  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 foreign markets are generally valued at
the preceding closing values of such securities on their respective exchanges or
if after the close of the foreign markets, but prior to the close of business on
the day the securities are being valued, market conditions change significantly,
certain foreign securities may be fair valued pursuant to procedures established
by the Board. 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 valued at their fair value 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
valued  at their  fair  value  as  determined  in good  faith  under  procedures
established by and under the general  supervision  of 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.

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


                                       9

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,  2005,  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, 2005,  there were no open forward  foreign  exchange
contracts.

FOREIGN CURRENCY TRANSLATIONS.  The books and records of the Fund are maintained
in United States (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  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. 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 shown as
"custodian fee credits".

DIVIDENDS AND  DISTRIBUTIONS  TO  SHAREHOLDERS.  Dividends and  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  equity accounts in the period when the
differences arise. These reclassifications have no impact on the NAV of the Fund
and  the  calculation  of net  investment  income  per  share  in the  Financial
Highlights  excludes  these  adjustments.  For the year ended December 31, 2005,
reclassifications  were made to decrease  accumulated  net investment  income by
$5,102 and to decrease  accumulated net realized loss on investments and foreign
currency transactions by $5,102.

The tax character of  distributions  paid during the fiscal years ended December
31, 2005 and December 31, 2004 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.

As of December 31, 2005, the components of  accumulated  earnings/(losses)  on a
tax basis were as follows:

             Undistributed ordinary income ....................    $      2,559

At December 31, 2005,  the Fund has net capital loss  carryforwards  for Federal
income  tax  purposes  of  $10,651,599,  which are  available  to reduce  future
required  distributions of net capital gains to shareholders.  $2,699,577 of the
loss  carryforward is available  through 2009;  $5,226,116 is available  through
2010; and $2,725,906 is available  through 2011. For the year ended December 31,
2005, the Fund utilized net capital loss carryforwards of $1,904,165.

3.  INVESTMENT  ADVISORY  AGREEMENT.  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.

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,  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 year ended December 31, 2005, other than short-term  securities,  aggregated
$10,120,028 and $11,053,743, respectively.

6.  TRANSACTIONS  WITH AFFILIATES.  During the year ended December 31, 2005, the
Fund paid  brokerage  commissions  of $229 to Gabelli &  Company.  Additionally,
Gabelli & Company  informed  the Fund that it  received  $2,810  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 year ended
December 31, 2005, the Fund  reimbursed the Adviser  $45,000 in connection  with
the cost of  computing  the  Fund's  NAV,  which is  included  in  miscellaneous
expenses in the Statement of Operations.

7. LINE OF  CREDIT.  The Fund has  access to an  unsecured  line of credit 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. At December 31, 2005, there were no borrowings outstanding
from the line of credit.

The  average  daily  amount of  borrowings  outstanding  from the line of credit
within the year ended December 31, 2005, was $170,418,  with a weighted  average
interest rate of 3.82%.  The maximum amount borrowed at any time during the year
ended December 31, 2005 was $1,680,000.

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.  Class
AAA Shares are offered only to investors  who acquire them directly from Gabelli
& Company or through  selected  broker/dealers  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 original  purchase or at the date of redemption,  based on the length of time
held. Class C Shares are subject to a 1% 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.

Effective June 15, 2005, the Fund imposed 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  within 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 years ended  December 31, 2005 and December 31, 2004 amounted to
$2,588 and $52,949, 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 have received  subpoenas from
the Attorney  General of the State of New York and the  Securities  and Exchange
Commission (the "SEC")  requesting  information on mutual fund trading practices
involving  certain  funds managed by the Adviser.  GAMCO  Investors,  Inc.,  the
Adviser's  parent  company,  is responding  to these  requests for documents and
testimony.  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,
2005,  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 periods indicated  therein.
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,  2005,  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,  2005,  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 periods  indicated  therein,  in  conformity  with U.S.  generally  accepted
accounting principles.

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

- --------------------------------------------------------------------------------
                   2005 TAX NOTICE TO SHAREHOLDERS (Unaudited)

   For the year ended  December  31,  2005,  the Fund paid to  shareholders,  on
   December 28, 2005, an ordinary income  dividend  (comprised of net investment
   income) totaling $0.0865, $0.0746, and $0.0443 per share for Class AAA, Class
   A, and Class C,  respectively.  For the year ended December 31, 2005, none 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, 2005, the Fund passed
   through  foreign tax credits of $0.0482 per share to Class AAA,  Class A, 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 2005 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 2005 which was derived from U.S.  Treasury  securities  was 0.77%.  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 2005. 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.

          was zero percent (0%).

     (g) The aggregate non-audit fees billed by the registrant's  accountant for
         services  rendered to the registrant,  and rendered to the registrant's
         investment  adviser  (not  including  any  sub-adviser  whose  role  is
         primarily portfolio management and is subcontracted with or overseen by

         sub-adviser  whose  role  is  primarily  portfolio  management  and  is
         subcontracted with or overseen by another investment adviser),  and any
         entity  controlling,  controlled  by, or under common  control with the
         investment  adviser that provides  ongoing  services to the  registrant
         that were not  pre-approved  pursuant to paragraph  (c)(7)(ii)  of Rule
