I love Johnny Cupcakes t-shirts and Make Cupcakes Not War is not only a lot of fun, it has a great message too. Everytime I look at his shirts I wonder how long he can sustain the cupcake metaphor, it seems he’s already done it for an impossibly long time, even building brick and mortar stores around it on some pretty expensive real estate on Boston’s Newbury St. I guess the constraint of using cupcakes in all his designs becomes a boundary against which his creativity, or that of his team can thrive. I’ve always heard that the best designs come from the best defined problems, design often thrives inside well defined constraints. Can anyone think of similar t-shirt companies so dedicated to a theme?
