Thuvia Maid of Mars

Ballantine 01524. 1969. Cover art by Bob Abbett. The Abbett series was originally published in 1963, with a second edition in 1965. In 1969 Ballantine decided to replace the cover of 'Thuvia Maid Of Mars' with the extra cover - now known as the rare 'Variant - to give it what was considered then to be a 'sexier' image.
