Anthony Kim has a cult following among golf fans. In his short career, he won 3 PGA Tour events, starred in the Ryder Cup, finished 3rd in the Masters, and had two Top 10s in the Open Championship. Then he stopped playing due to an injury in 2012 and has never played again. In fact, Anthony Kim has apparently never signed an autograph or even given an interview since he left the game of golf.

Offered here is a rare single-signed Anthony Kim autographed Masters flag.
