Two-book set of golf swing instruction books by David Leadbetter. "The Golfing Machine" and "The Ultimate Practice Routine" There is some wear and tear, but the inside is relatively clean with no noticeable stains or damage. Both books are composed of beautiful photographs and easy-to-understand explanations, and I think they will be helpful to a wide range of people, from beginners to single handicappers. Will be sent in simple packaging via Yu-Packet Post. Please take a good look at the photos and consider purchasing.
