Willie Park was a great golf ball innovator and he designed and produced two pretty exceptionally pretty golf balls - the Diamond Mesh and the Park Royal. The Willie Park "Diamond Mesh" received a patent in October 1890 - a full six years before the famed Park Royal was produced. (The Story of the Golf Ball by Kevin McGimpsey, p. 187). Few Park Diamonds are known to exist, and even fewer with any significant amount of paint, as the paint application on 1890 golf balls with complex patterns was not ideal. The offered example retains 95% of its original paint.

This ball was last sold at the November 1997 Phillips Auction, and was featured on the back outside cover of the auction catalog.
