This 1953 1st Edition, Third Printing of How to Play Your Best Golf All the Time is autographed inside by both Tommy Armour and Claude Harmon. Autographs of "the Silver Scot" Tommy Armour are hard to find, as he passed away in 1968. But autographs of 1948 Masters Tournament Champion Claude Harmon are truly scarce. It is the Masters Champ signature missing from almost all collections. Both autographs accompany a note to the recipient, and Harmon's is simply signed "Claude."
