Three of the greatest golfers of all-time signed this yellow Masters pin flag. Arnold Palmer signed on the top, Tiger Woods in the middle and Jack Nicklaus on the bottom. All three signed in bold black ink and in our opinion the signatures rate a combined 9. On the bottom left of the flag is a JSA sticker serial number “B51823”, an Upper Deck hologram serial number “SHO24528” and an additional sticker. Accompanied by a Full LOA from JSA.
