This Autographed Bobby Brown Oal Baseball has been Personally Signed by Mike Davis of the Oakland Athletics. This item is 100% Authentic. This item may come with the new Beckett Authentication hologram that has a scannable QR code rather than the traditional COA. If you would like to have a COA, you are welcome to reach out to Beckett for a printed certification once you receive your item. We have multiples of this same item. While the photographs are representative of this item, the size, placement and strength of the signature may vary. Each item is hand signed, therefore, each autograph is unique. Please know, these are vintage baseballs, and will have some spotting and toning throughout. Please reach out to us with questions prior to purchase.
