Where can I download the exact same clip art used by David Rees to
construct his Get Your Own War Own comic strip panels? Not looking for
a list of clipart sites, as I've already spent hours poking through
them looking for this

I have written to the artist, here is his response:

You can find most of the images in the collections published by Dover.
They are a major source of public domain clip art.

Best regards,
David Rees

Also...here is a relevant link to the CD Rom that contains Dover's Business Images:

Hope this helps.

Very resourceful. Excellent work. How do I accept this answer?

Canadianhelper: Incidentally, did David Rees give you that link or did
you find it yourself?

Hello...

I am an unpaid commentor...thanks for the thought...

David Rees did NOT provide the link..you may wish to go through
Dover's catlog of CD's OR most of their stuff is in print form that
you could browse at a Barnes & Noble/Chapters big box book store then
narrow down from there....I just dug around on the Dover site and that
really seems to be the CD with the most likely fit.

Sorry I didn't make it clear that the link was my sentence.

Oh....

To 'accept' the answer I think you 'cancel' the question (again, I am
not officially with the google answer team so I might be
incorrect)...it will still cost you the .50 posting fee.  Here is a
snippet from the google answer FAQ:

I posted my question and a registered user answered it in a comment.
Can I cancel my question?
