This week’s tee is another obscure pop cultural reference courtesy of R. Stevens, creator of the comic strip Diesel Sweeties. On the surface, it appears to be a rather strangely symbolized expression of your love for astronomy. To the pattern-recognizing comic book geek, it is an homage to one of the most terrifying and absurd creations ever to spring from the minds of Stan Lee and Jack Kirby–Galactus, Devourer of Worlds.

If you’re saying to yourself right now, “Hey, isn’t Galactus just a big cloud that the Silver Surfer blew up in Fantastic Four 2?” you can turn in your geek credentials right now. The true Galactus is purple, humanoid, and wears a bizarre tuning-fork helmet. Accept no substitutes. Also, buy this shirt now, as it’s a limited edition that goes off the market on May 26, 2008.
