There have been a couple of issues of Mudcat T-Shirts. Surely the image/art used for them would be larger (requiring more pixels) if one can be found.

Discussion of a "Mudcat T-Shirt" appeared way back in T-Shirts Date: 26 Jul 97 - 02:26 PM, with comment from Max:

I have an artist drawing up a few catfish doing various things. I am partial to one playing a fiddle aside the delta. We will certainly have multiple versions and let you all vote on them before we commit.
Soon...

Obviously this was before the catfish logo appeared, but one wonders what happened to all the other suggestions that people apparently sent in. [?????]
