Mint Ocobo Gutty Ball in the Wrapper. The Real Deal. Manufactured by James B. Halley & Co out of London in 1894, featuring a molded mesh/"bramble" pattern. Golf Illustrated wrote of it in 1901, "Some of the new balls have puzzling names, and a great diversity of opinion exists as to their proper pronunciation. Thus the "Ocobo" is pronounced sometimes with all the vowels short, and sometimes with the second one long. The name is believed to have some occult reference to Colonel Bogey...."
This ball is shown to the far right in the 2nd from the top row in the accompanying group image.
