Ace Science Fiction Classic 1960s Edgar Rice Burroughs paperback book edition w/ Frank Frazetta art (see below)In the early 1960s, Ace Science Fiction Classics introduced a new generation to Edgar Rice Burroughs' beloved Tarzan—with Frank Frazetta's cover art (and title page illustrations) luring in readers with his extraordinary work. Frazetta had just started painting with oils at this point in his career, and these legendary Ace commissions turned the artist into a major pop-culture figure. Books in this popular series are seldom found in high gradings.
