This is an original circa 1930 Type 1 photograph of Sunningdale Golf Club that is autographed on the back by famed golf course architect Harry S. Colt. Though autographs of his contemporaries like Alister MacKenzie and C.B. Macdonald are fairly rare, signatures of Harry Colt are almost non-existent. In fact, this is only the 3rd authentic example we've ever encountered. 7 x 9 5/8".
