I am trying to sell my Muhammad Ali and Joe Frazier 16x20 which is autographed by both. Ali's autograph also says "AKA Cassius Clay". I really don't want to send t out to get a Certificate of Authenticity. I never did it in the first place because I never thought I would be selling. I got the autographs in 1996 at a Card Show in New Jersey that actually featured the Dalas Cowboys. I can't find the pictures of Ali signing my picture. How can I post this to eBay and have people believe it is real without a COA. I have included pictures of the item if anybody wants to give their thoughts on authenticity.
