A 1986 John Madden Signed “One Knee equals Two Feet” Autograph Book with one of the most Incredible Inscriptions I have ever seen on a book. The Inscription Reads To Jim Barrett, Your new replacement Knee equals two Feet. If you replace your other knee you will have Two more. With four feet you will be twice as fast as any of those yoyo’s you play tennis with. Good Luck, John Madden. It’s just an Incredible Inscription which Brings back memories of how only John Madden could talk lol. This Book has a tear in the dust jacket and some soiling mainly noticeable on the back dust jacket cover and is not in perfect condition but the Autograph page is Beautiful and overall is a nice solid book for being almost 40 years old and everything considered.
