In early 1967, Karsten Solheim entered into an agreement with Mark McCormick, the agent for Jack Nicklaus and Gary Player, that allowed Slazenger of England to sell PING putters bearing the endorsement of Nicklaus.  This agreement lasted approximately three years.   ( see And The Putter Went Ping p 92-94, 100.

The Jack Nicklaus Kushin was introduced in mid-1965 and sold by Slazenger under the agreement referenced above. It looks great and presents well.  The sight line on the top of the head is original to the club.  The 35-inch original shaft still has some of its original Slazenger shaft band, its original Golf Pride Informer grip, and its ping grip collar.

Jack Nicklaus PING putters are wonderful history and eminently collectible.
