This is one of the most difficult Masters Champion single signed flags around - an undated Masters flag autographed by Byron Nelson in the center. "Undated" Masters flags are coveted by autograph collectors, and this version was sold at the 2002 Masters Tournament. By then, Byron Nelson had all but completely stopped autographing Masters flags, so it was not an easy task to obtain an autographed flag like this prior to Byron Nelson's passing in 2006.
