Sheldon Coopers 'Superman DNA' Shirt

Sheldon wears a few different colored versions of this same shirt featuring Supermans DNA. From what I understand, this t-shirt was initially sold from TheComicCenter.com, but their website has since vanished like a fart in a breeze. I'll keep my peepers open in case someone else comes along to create a replica. Until then, if anyone has any suggestions be sure to fill me in.
