In 2016, Arnold Palmer attended The Masters Tournament for the final time. Per tradition, he was scheduled to his the ceremonial tee shot alongside Jack Nicklaus and Gary Player. But Mr. Palmer wasn't feeling well, so he attended the morning ceremony, but did not swing a club. Though we didn't know it at the time, the 2016 Masters would be Arnie's final Masters. 

Because of his health, we doubt that Arnie signed many autographs at the 2016 Masters Tournament. However many he did sign, the offered flag is certainly one of the finest. This 2016 Masters flag is autographed in the center by The Big Three - Arnold Palmer, Jack Nicklaus, and Arnold Palmer.
