Johnny Miller's final round 63 during the 1973 US Open at famed Oakmont Country Club is considered perhaps the greatest single round in golf history. Offered here is an official scorecard from Oakmont that is beautifully autographed by Johnny Miller, who has added a notation "1973 U.S. Open Champion". Miller also signed the reverse of the scorecard and added the notation "63" in reference to his legendary final round score.
