1957 was Ken Venturi's first full year as a professional. Pictured below is his Tournament Scorecard from the 57 Western Open where he was paired with fellow World Golf Hall of Fame inductee Julius Boros. Given that Venturi retired from professional golf in 1967, his signature on a Tournament Scorecard is particularly rare. This scorecard resides in a private collection (collector wishes to remain anonymous). Estimated Value - $2,500 and Upwards.
