Robert Clark was a publisher and well-known golfer of his day. He collected what was known about golf history in 1875, when golf was gaining popularity, and accounted it all in his storied book, Golf, A Royal and Ancient Game.
Here we have a scarce 1875 First Edition, of which there were only 200 produced! It has just a couple condition issues, with the end paper on the book being separated but present, and the spine and binding somewhat loose. GilChrist's Guide to Golf Collectibles lists this edition at $2,500.
