Artist Travis Pitts combines some of his favorite things in this illustration: tough chicks, childhood memories, and zombies. Designed for cult t-shirt company Threadless's horror contest, Velma and Scooby Doo take on a leaner, meaner form as they are the only survivors of the "Monsterpocalypse" – noted by the "RIP S-F-D" emblazoned on the newly-christened Misery Machine. Pitts modeled the heroine on his own girlfriend, who struck the pose with an umbrella in lieu of a shotgun. The tee is available in both guys and gals' sizes.
Uh oh - looks like they sold out of this one. Here are a couple of other good Threadless shirts, though feel free to browse their enormous catalog for lots more.
"The Red," a.k.a. Little Red Riding Hood with a chainsaw.
"In Case of Zombies."
