Karsten Solheim first produced the Ping 69 putter in 1961. The inspiration came from his son Allan, who suggested that Karsten make a putter with a heavy flange. The original 69 putter was then followed up with several variations.
The 33 1/2" shaft, with a single bend down by the head, is original as is the Golf Pride Informer grip. The grip collar is no longer there, but its impression remains at the base of this grip.
John Barnum used a Ping 69 putter to win the 1962 Cajun Classic and become the first golf pro to use a Ping putter to win a PGA Tour event. This club is a fine example with a clean head. For more information see "And the Putter Went Ping" p56-59.
