I got this wallet as a gift but it has this symbol on the front that I don't recognise. It's a nice enough wallet, I just want to make sure I don't get caught in the middle of a gang war if I take it out in the wrong part of town and I didn't know what I was supporting with the symbol. Get it? Of course, it could just be a random symbol but it looks familiar. Anyone know what it is or what it means?
