1. Scanned pictures of Hal Jordan getting hit in the head, like this one which was a present from Kalinara. [This one's particularly nice, because (a) that's Kyle hitting Hal with a lead pipe (b) at this point in his career, Hal's been konked so many times he can't even feel it any more). If you don't have any comics that contain pictures of Hal getting hit in the head, original fan art of Hal getting hit in the head (preferably by something yellow or otherwise embarrassing) will do.
2. Scanned pictures of Vibe. As unlikely as it may seem, I have only ONE issue of the Detroit League, which featured Vibe. Perhaps that's why I like him so much? Anyway, any picture of Vibe will do. If you're moved to get rid of your Detroit-era league issues of JLA, but the EPA won't let you dispose of them at any federal facilities, you can send those to me, too! You can't imagine the joy they will bring me. In fact, it's best if you don't think about it.
