I happen to be looking for an authentic Chris Evans autograph, and stumbled upon this monstrosity. If you look back at what this guy has sold, it's just depressing. People are actually bidding on this garbage! Every signature is signed by the same person.

This one is particularly laughable. You don't even have to know the cast's signatures to tell this is fake.
