Well, this thread looks like it could use a bump.
I'm not sure if this is even a relevant idea. I remember Lincoln Enterprises making a set of TOS business cards way back in the 70's.
I have never seen any from the NG, VOY, DS9, TAS, etc.
How about a set form one (or all) of these incarnations?
I realize there isn't a lot of "art" involved but designing a good business card isn't always easy.
