This Autographed Riddell Authentic Full Size Speed Rep Helmet has been Personally Signed by Ndamukong Suh of the Nebraska Cornhuskers. This item is 100% Authentic to include a hologram by James Spence Authentication Services. This item will come with an affixed James Spence Authentication Services (JSA) authentication sticker, which includes a scannable QR code to verify authenticity. Please note that JSA no longer provides serial-numbered COA cards with witnessed items, and the attached JSA sticker will serve as the complete authentication for this item. This is a JSA Witnessed Protection Program item which means a JSA representative was present when this item was being signed. We conducted an autograph signing with Ndamukong Suh 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 JSA Witness.
