Back in July Michael linked to a couple of shirt designs by Kerry Callen (one of our favorites) that were up on Threadless for scoring. Both were eventually printed by Threadless; the female version was available in limited quantities at the Cincinnati Comic Expo, while the male version is available now on the Threadless site.
Brain Wood's Northern Boy T-shirt line is back in business, and he recently added two shirts that would be of interest to DMZ fans -- an "Inspired by Matty" press T-shirt, and an "Inspired by Zee" Union Jack muscle shirt. He's got both of them, plus more shirts, books and original art, at the Northern Boy shop.
And finally, Shirts for a Cure, a nonprofit that sells music shirts to raise money to fight breast cancer, will have a booth at the New York Comic Con next week and will sell several con-exclusive shirts. They include the above SHIELD-related shirt, an official Hellboy one and a cool Savior 28 design by Mike Cavallaro. They have several more science fiction-themed shirts up on their Facebook page. If you're going to the con next week, they'll be at booth #1003.
