This is a set of two golf swing instruction books by David Leadbetter. "The Lessons of the Kingdom" and "The Ultimate Practice Method." There is some feeling of use, but the inside is relatively clean with no noticeable dirt or damage. Both are composed of beautiful photographs and easy-to-understand explanations, and I believe they will be helpful for a wide range of people, from beginners to single handicappers. Will be shipped in simple packaging via Yu-Packet Post. Please examine the photos carefully and consider your purchase.
