Marauder tattoo help please?

I'm thinking about getting a tattoo, and I'm leaning toward a Harry Potter one, probably something to do with the Marauders. If I decided I wanted one specifically that had a Sirius Black reference, what do you guys think it should be? I don't think I want one with his face, but I'm not sure what else I could get. Maybe a quote or symbol or something? Please help me out! One that has a general Marauder reference would work too.
