Has this seller been brought up? I've seen nothing but questionable material from them. They also sell on Amazon.
For example, this Garbage signed photo is unquestionably a forgery. Not well done at all, and not convincing to any actual fans of this band. Since they say they saw it signed in person themselves, I guess that incriminates them as the forger (or a liar - it's one of those two choices).
I'm surprised this seller is doing as well as he is.
IMO, I've noticed that seller offering quite a number of forgeries too. It surprises me that eBay hasn't suspended him long ago, but I guess when you're listing an average of 3,500+ items, it's easy for them to turn a blind eye.
