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. The authenticity can be verified on Beckett Authentication Services website. This is an original University of Oklahoma envelope that had Shaquille O'Neal's recruitment letter. This is just the signed envelope, and it will not come with its original mailings. This was kept in O'Neal's personal collection, but it will not have a letter of provenance.
