This Autographed White Pinstripe Pro Style Jersey has been Personally Signed by Mariano Rivera of the New York Yankees. This item is 100% Authentic to include a hologram by Beckett Authentication Services. This item will come with an affixed Beckett Authentication Services (BAS) authentication sticker, which includes a scannable QR code to verify authenticity. Please note that Beckett no longer provides serial-numbered COA cards, and the attached BAS sticker will serve as the complete authentication for this item. This is a BAS Witnessed Protection Program item which means a Beckett Authentication Service representative was present when this item was being signed. 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. This is a X-Large sized, non-branded, custom-stitched Jersey.
