Ben Hogan Signed Official Scorecard
from 1951 US Open

Well take a look at this gem. Offered here is a rare official scorecard from the 1951 US Open at Oakland Hills, which was completely hand-filled with Hogan's scores and then signed by Ben Hogan himself. This practice of filling out the scores and essentially making a duplicate of the original scorecard for friends/relatives was a relatively common practice in years past, and we can only presume that that's exactly what happened here.

This original 1951 US Open scorecard has been matted for easy framing, and both sides of the scorecard are still visible with the mat.
