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. pp93-94)  By mid-1967, the PING Echo was in Karsten's arsenal. Today, it is among the rarest Nicklaus-endorsed PING putters.

The 35 1/2" shaft is original and still has its original shaft band, white Golf Pride Informer pistol grip, and grip collar. The head is in clean condition.
