Go there and they will help you out, but always get a second opinion from somewhere else. You can also go to a pawn shop and they usually have someone they call to Authenticate the signature and tell you how much it's worth if you want to sell it
They have a company called JSA that authenticates items. They will be there in May. You can also bring it to their shop and the owner can give you an idea if it's legit. His name is kendal
