From CARTOONING THE HEAD by FIGURE by Jack Hamm. (1916-1996)An outdated book from the days when the manuals were SUPPOSED to be superior to what the student's level was, instead of coddling it. I've always found Mr. Hamm's female abstractions to be extremely sexy, and I've found his teachings indispensable.
