This is an 8x10 Photo that has been hand signed by Jim Kaat. This item has been certified authentic by Beckett Authentication (BAS) and comes with their tamper-proof 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.
