This Autographed Grey Pro Style Jersey has been Personally Signed by Ozzie Guillen of the Chicago White Sox. This item is 100% Authentic to include a Certificate of Authenticity (COA) / hologram by JSA Witness or Beckett Witness. This is a Beckett Witnessed or JSA Witnessed Protection Program item which means a Beckett or JSA representative was present when this item was being signed. 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 stock item in which we have several available. We have taken part in multiple autograph signings with Ozzie Guillen 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 or JSA Witnessed. This is a X-Large sized, non-branded, custom-stitched Jersey.
