To our knowledge, this is an unlisted book published for the 1931 Open Championship at Carnoustie, which was produced by the Merchants Association of Carnoustie. The first page of the books says "Come to the Open Golf Championship at Carnoustie 1931" and the second calls it the "Carnoustie Official Guide Book." Good condition but cover has pulled away from the staples. A few pages are loose but overall they are good. Very rare.
