Online I found an overview of the following books by Choi Hong Hi: Taekwon-Do - The Art of Self-Defence - 1965 Taekwon-Do (The Korean Art of Self-Defence) - 1972 (6 Editions & 2 Reprints 1972-1986) Encyclopedia of Taekwon-Do: 15 Volume Set - 1983 (5 Editions 1985-2008) Condensed Encyclopedia - 1988 (6 Editions) Are the number of editions and timeframes above correct? Is there a later version of the Condensed Encyclopedia than 2003? I own the 1965 book and the 1972 edition of "Taekwon-Do (The Korean Art of Self-Defence)" plus a PDF version of the Encyclopedia. I'm wondering, which edition of "Taekwon-Do (The Korean Art of Self-Defence)" was the first to feature the Juche Tul and the sine-wave motion. Does somebody have it handy and can look up the year it was published and let me know about the color of the book and the color/picture of/one the dust jacket? Thanks!
