This is something we've often dreamed about, but never knew existed until recently. To many, this is golf autograph collecting's Holy Grail. Offered here is an original scorecard from Augusta National Golf Club that is autographed by all 5 men that have completed the career Grand Slam - Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus, and Tiger Woods.
We can only presume that this is the only example autographed by all 5 Grand Slam Champions that exists in the world. And with Ben Hogan passing away in 1997 and Gene Sarazen in 1999, this is almost certainly the only one that will ever exist.
This autographed scorecard has an impressive amount of authentication, including an early 2000s hologram from Tiger Woods as to his own autograph, a Jack Nicklaus Golden Bear hologram as to his autograph, and a Letter of Authenticity from James Spence Authentication (JSA) for all 5 autographs.
