Official undated Masters flag that is autographed in the center by 1979 Masters Champion Fuzzy Zoeller, who also added a notation with the date of his victory. As flag collectors are well aware, it is quite difficult to get (a) a full-signature Fuzzy Zoeller autograph, (b) in black Sharpie (he likes to sign in red), and (c) in the center of the flag.
