Attempts to collect autographs of famous golf course architects often stop when trying to locate a Harry S. Colt signature. Though signatures of contemporaries like Alister MacKenzie and C.B. Macdonald are indeed rare, Harry Colt autographs are virtually nonexistent in the collecting market. Other than the offered example, we've only seen one other authentic Harry Colt autograph. This Colt autograph is dated 1906 - dating to Colt's golf playing career and before his design career.
