Topic: B'BC autograph true or false?

Hello, I collect replicas of James Bond objects and autographs, one of the biggest sellers of James Bond autographs is the B'BC sit, either directly via its site or via ebay (24,000 positive reviews) I just saw on a facebook page a person selling B'BC autographs and a great collector whom I respect questioned the honesty of B'BC. What do you think? Can we be confident? have you ever had any problems? Have a good day
