By Norman Leff. #324. 7 X 10, 150 pages, paperback. ISBN #0-86568-190-2. Norman Leff began his training in martial arts over 50 years ago. Back in the days when Asian martial arts were considered mystical and mysterious concepts, Leff was already earning his first black belt. His training took a dramatic turn when, in the 1960s while living in Colombia, South America, he met a former Royal Japanese Marine who revealed to him the secret aspects of jiu-jitsu taught only to the military, but not to the public. Later, as a bouncer in New York city, Norman put his training to the test. Now, he's ready to share these secrets with you! Learn the atemi-waza
