I don’t know where to buy this T-Shirt but I love it, I especially love the picture of the kid wearing it, so awesome. I’ll give a $25 Threadless Gift Certificate to the first that links in the comments to where you can buy the original version of this shirt.
Looks like the original (or at least the one pictured) is from defectivewear.com
Cory also suggested this one in the comments.
Which came first though?
UPDATE: ok, looks like the Destroy All Monsters version is the original, created in 2007 as opposed to Defectivewear which is dated 2008, Cory wins
