I bought that “book” out of a T.V. Guide back in 1973.Somwhere around there.There was only 2-3 actual defense techniques included.A couple of trick breaking techniques, and the rest was a series of ripping, eye gouging,and smashing techniques all aimed at the face.It was badly photo copied ,folded and stapled in the middle.Although the product itself was cheaply thrown together,It was one of the more brutal,no fluff manuals I've ever seen.
