This is a 16x20 Photo that has been hand signed by Gary Payton. This item has been witnessed and certified authentic by Beckett Authentication (BAS) and comes with their tamper-proof witness sticker. Beckett Authentication has recently changed their physical certificate card policy where they no longer match their tamper-proof sticker with a physical certificate. The tamper-proof sticker holds the value in the authentication process while the certificate does not. A certificate can be printed on Beckett's website for the matching authentication number.
