That stuff is really cool! I can't think of any ideas right now for you but if I do I'll let you know! But about the wanted signs, do you think you could make your own? They don't have to look "real" even..it would be cute to just put his picture on a tanish colored piece of paper..maybe burn the edges of it to make it look worn, then type or write Wanted for blah blah blah.
