I think we should stop questioning one of the best members on this forum, and keep the discussion to the signing. Where zechautographs gets autos really isn't anyone's business but his own. He can do what he pleases, and I for one am glad he is a member of this forum. His threads are the most interesting to read.
I guess I agree with the fact that Josh would in fact sign the items, so there wouldn't really be a contract needed. However, I brought this up in the other thread about authenticity, and it still holds true. Unless you witness the signing, it could've been signed by someone else.
