Nicknamed the “Golden Bear”, Jack Nicklaus is arguably the biggest star in the golf world. Here is a chance to own a tournament worn polo signed by Jack himself. This yellow polo featuring a white stripe on the collar is a must-have for any golf collection. When it comes to the Major Championships on the PGA Tour Jack is the most dominant golfer ever. For example, at the 1965 Masters, Jack finished 9 shots ahead of the runners-up with a record core of 271. The following year he won the 1966 Masters as well, making him the first golfer to ever achieve back-to-back Masters wins. His signature is deemed authentic by virtue of Upper Deck Authenticated’s Five Step Process.
