The Johnny Cupcakes ‘Creature’ Shirts are the first in a series of collaborations with illustrator Thom Glick, called ‘There’s Something In The Cupcake Mix!?!’ They are four halloween-ish style characters printed on t-shirts, and each shirt comes inside a matching cupcake mix box. Each box will have a cupcake scented scratch and sniff sticker, monster trivia and a bit of baking flour inside- so you have to actually dust baking flour residue off your t-shirt before you wear it. The whole series is limited to 300 shirt and box combinations for each design. The big release party is tomorrow at 7pm on, wait for it, Friday, October 13th at the Boston location: 279 Newbury Street. More exclusive shirt pictures after the jump.
