This is an original pairings sheet from the 1942 Masters Tournament that is autographed by that year's Masters Champion Byron Nelson, as well as Bobby Jones, Gene Sarazen, and Sam Byrd. These autographs were almost certainly obtained at the 1942 Masters, making this piece even more special. Pre-war Masters Tournament items are incredibly rare. This pairings sheet also has a wonderful early map of Augusta National Golf Club on the reverse. Note the old name "White Pine" for the 1st hole, not its current (and longtime) name Tea Olive. 

This was recently submitted to PSA, which authenticated the autographs and encapsulated the Pairings Sheet. This is surely one of the only pre-war pairings sheets signed by the winner of that year's Masters Tournament.
