I think this might be the cleverest product Marvel ever produced. It's hilarious. Rip Off
I saw a guy wearing one at the last Cincy Expo (presumably a re-released version). When he was walking our way, I whispered to my son to turn around and look at his shirt after he passed us figuring they wouldn't skip the back part! They didn't. It was there all right! We laughed.
Either Zazzle or some site makes them, but I bought the two-sided Ben Grimm design as a t-shirt a few years back (the one with 'if you can read this...' on his backside..). Awesome quality.I should track down which site, because I'd LOVE to get more of the MMMS-era shirts..
