"I have never done many “mash-up” shirts, but this idea seemed simple enough to work for me because it’s two ideas I can stand for: Firefly and the Peanuts. Both rock, both are awesome. So why not merge them in one design? I also feel both “gangs” have things in common – they argue, they make each other angry, they have adventures together and in the end they stick together. The execution of the design was easier than I thought, it works with my “cute” drawing style." - queenmob
