This may be one of the most unique items the memorabilia market has ever seen! This CUSTOM made 1/2 Raiders 1/2 Royals Split Jersey has been personally hand-signed by Two Sport Legend Bo Jackson. We have added the 1989 MLB All Star Game Patch to the baseball sleeve and the 1991 Pro Bowl Game patch to the football to make this item even more over the top! This item was signed in the presence of and witnessed by a representative of Beckett Authentication. It comes with an individually numbered, tamper evident sticker from Beckett which can be reviewed online to ensure authenticity. This process helps to ensure that the product purchased is authentic and eliminates any possibility of duplication or fraud.
