The 'Golden Bear' Jack Nicklaus owned and used this Macgregor driver. The soleplate is stamped Jack Nicklaus and the transfer depicts the British Open claret jug trophy. Many regard the American as the greatest golfer of all time with 18 major titles including six US Masters, five US PGA Championships, four US Opens and three British Opens. Nicklaus endorsed MacGregor Golf's equipment for many years and later became a shareholder.
