Magic Carpet Burn has a great post about THIMK Magazine, from the late 1950's. I was around, but I was still primarily interested in SPOOKY, HOT STUFF, and some DC mystery comics.
I did find these Rapidshare links to more issues of THIMK and I tried to do a recreation of the t-shirt, with Otis Dracenstein's gruesome mug, offered from the old magazine. If there is any interest, I could offer it up at one of my online t-shirt sites.
SORRY, BUT THE LINKS TO RAPIDSHARE APPEAR TO HAVE EXPIRED. IF anyone finds good links to the files, I'll update these.
