Bruce Tegner / Thor Publishing (1961)
Summary: This is another of Tegner's quasi-Aikido self-defense books, many of which are simply reincarnations of previous books. What sets this book apart is the fairly accurate description of the nature of Aikido as a benevolent, non-violent art, and the very early date of publication (1961), which means that it pre-dates practically all other English-language mainstream publications pertaining to Aikido, except for a Tomiki book from 1956, a couple by Makiyama in the late 50's or 1960, and Tohei's first book in 1960. Collectible for this reason, contents notwithstanding.
