This is an original First Day Cover (FDC) from the grand opening of Augusta National Golf Club on January 13, 1933. Quite spectacularly, this FDC is autographed by the great Bobby Jones. Quite remarkably, PSA has authenticated Bobby Jones' autograph and graded it a perfect PSA 10 Gem Mint. In addition to PSA authentication, Bobby Jones' autograph on this 1933 Augusta National FDC also comes with a full letter of authentication from James Spence Authentication (JSA).
