This Autographed Black Riddell Full Size Speed Rep Helmet has been Personally Signed by Barry Sanders & Thurman Thomas of the Oklahoma State Cowboys. This item is 100% Authentic to include a hologram by Beckett Authentication Services. This item will 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. This is a BAS Witnessed Protection Program item which means a Beckett Authentication Service representative was present when this item was being signed. We conducted an autograph signing with Barry Sanders & Thurman Thomas where multiples of the same item were signed. 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 item can be verified through BAS Witnessed.
