18-time Major Champion Jack Nicklaus used this custom Slazenger "Jack Nicklaus" signature model 8 iron in the 1967 Open Championship, where he finished in 2nd place to Roberto De Vicenzo. This custom club is also stamped "JN 67", indicating Nicklaus' use of it during the 1967 season.

Nicklaus' set of irons from the 1967 Open were originally donated to a charity and then used as a competition prize. This spectacular Nicklaus tournament-used golf club was initially offered in the November 2007 Sotheby's auction in London.         

This Jack Nicklaus used British Open golf club is certainly a special one.
