account for the $3 million contingent payments as goodwill to the
extent that payments are made.  Please revise Note 5 to the

include disclosure of this accounting treatment.  See paragraph

F-
48 to F-49
7. We note that in the unaudited pro forma income statement for
the
six months ended June 30, 2006, on page F-49, there is an
adjustment
to eliminate the interest expense of both Innerworkings and
Graphography.  However, in the unaudited pro forma income
statement
for the year ended December 31, 2005, on page F-48, the adjustment
relates only to the interest expense of Innerworkings.  Please
explain the reason for the difference in these two adjustments.
Revise your notes to the pro forma financial statements to clearly
explain any adjustments made to Graphography`s interest expense.

      As appropriate, please amend your registration statement in
response to these comments.  You may wish to provide us with
marked
copies of the amendment to expedite our review.  Please furnish a
cover letter with your amendment that keys your responses to our
comments and provides any requested information.  Detailed cover
letters greatly facilitate our review.  Please understand that we
may
have additional comments after reviewing your amendment and
responses
to our comments.

      We urge all persons who are responsible for the accuracy and
adequacy of the disclosure in the filing to be certain that the
filing includes all information required under the Securities Act
of
1933 and that they have provided all information investors require
for an informed investment decision.  Since the company and its
management are in possession of all facts relating to a company`s
disclosure, they are responsible for the accuracy and adequacy of
the
disclosures they have made.

      Notwithstanding our comments, in the event the company
requests
acceleration of the effective date of the pending registration
statement, it should furnish a letter, at the time of such
request,
acknowledging that:

??should the Commission or the staff, acting pursuant to delegated
authority, declare the filing effective, it does not foreclose the
Commission from taking any action with respect to the filing;

??the action of the Commission or the staff, acting pursuant to
delegated authority, in declaring the filing effective, does not
relieve the company from its full responsibility for the adequacy
and
accuracy of the disclosure in the filing; and

??the company may not assert staff comments and the declaration of
effectiveness as a defense in any proceeding initiated by the
Commission or any person under the federal securities laws of the
United States.

            In addition, please be advised that the Division of
Enforcement has access to all information you provide to the staff
of
the Division of Corporation Finance in connection with our review
of
your filing or in response to our comments on your filing.

      We will consider a written request for acceleration of the
effective date of the registration statement as confirmation of
the
fact that those requesting acceleration are aware of their
respective
responsibilities under the Securities Act of 1933 and the
Securities
Exchange Act of 1934 as they relate to the proposed public
offering
of the securities specified in the above registration statement.
We
will act on the request and, pursuant to delegated authority,
grant
acceleration of the effective date.

      You may contact Claire L. Erlanger at (202) 551-3301 or
Lynwood
F. Shenk at (202) 551-3380 if you have questions regarding
comments
