Payne Stewart certified autograph 1991 NFL Pro Line Portraits golf card

Very rare 1991 Pro Line Portraits card autographed in thin black marker on the back by the late, legendary PGA Tour superstar Payne Stewart, embossed with the NFL's seal of authenticity in the lower right corner. Many of these cards have obvious edge chipping and/or a weak signature, this card is much better than most. ONLY ONE AVAILABLE FOR SALE.
