The product is a custom design jersey signed by basketball legend Larry Bird. The autograph is authenticated by Beckett Authentication Services (BAS) and comes with a Certificate of Authenticity (COA) number 1W298524. This unique item is a must-have for fans of the Boston Celtics and NBA Championship. Made in the United States, this  autographed jersey is a valuable piece of sports memorabilia. I FOUND NO PRODUCT NUMBERS AT BOTTOM OF JERSEY WHICH LEADS ME TO BELIEVE JERSEY IS REPLICA.  HOWEVER, I DID SOME CHECKING ON THE BECKET NUMBER.  LARRY DID DO SIGNINGS IN COLUMBUS, INDIANA IN AUGUST OF 2024.  SIMPLY PUT, REPLICA JERSEY AND REAL SIGNATURE.
