This is an original member's jacket from Muirfield Village Golf Club. Jack Nicklaus' Muirfield Village is one of the United States' preeminent private golf clubs, and has hosted the Memorial Tournament each year, as well as such tournaments as the Ryder Cup (1987), US Amateur (1992), Solheim Cup (1998), and Presidents Cup (2013). 

Needless to say, actual members' jackets from Muirfield Village simply do not ever come available on the collector market. This 43 XL jacket comes from the Estate of former World Golf Hall of Famer Bill Campbell, who was presumably a member at Muirfield Village.
