Jones also founded Masters tournament in 1934. Extremely rare golf ball signed in fountain pen, “With best wishes - Sincerely - Bob Jones.” The ball has been mounted to a wooden plaque (with back half of the ball recessed into the plaque) and lettered at the bottom “World’s Greatest Golfer.” In very good condition, with a surface mark affecting a single stroke of last name of signature, expected light skipping to signature and sentiment from dimples, light overall surface crazing to ball and a light shade of toning. Bobby Jones signed golf balls represent one of the great rarities of golf collecting. Very few examples are known, literally a handful, and this is the first one we have ever offered.
