I've been doing some research through federal publications & it looks like the MAME art logo is copyrighted by the original person that made it.
http://www.copyright.gov/circs/circ1.html#wccc"Copyright protection subsists from the time the work is created in fixed form. The copyright in the work of authorship immediately becomes the property of the author who created the work. Only the author or those deriving their rights through the author can rightfully claim copyright."
It falls under:
"pictorial, graphic, and sculptural works"
FYI:
"The 1976 Copyright Act defines publication as follows:
"Publication" is the distribution of copies or phonorecords of a work to the public by sale or other transfer of ownership, or by rental, lease, or lending."
"Before an infringement suit may be filed in court, registration is necessary for works of U. S. origin."
To register a work, send the following three elements in the same envelope or package to:
Library of Congress
Copyright Office
101 Independence Avenue, S.E.
Washington, D.C. 20559-6000
A properly completed application form.
A nonrefundable filing fee of $30 for each application.

So whoever made that graphic needs to send $30 in and then file an infringement suit against Foley. The suit will allow collection of all lost money. (like the money Emdkay and those other guys were *ahem*about to start paying for using that graphic). That will allow the printer guys to also file an infringement suit. That assumes that they have come to an agreement regarding royalties to the original author. I thought I heard a rumor it was like $30 or something.

I'm sure ya'll can work something out.
