The Cave Girl series lasted just four issues. Published by Magazine Enterprises between 1953 and 1954, this was the third issue (despite being number #13*). All interior and cover art is by Bob Powell.
Powell might be most famous for creating GGA jungle superstar Sheena for Fiction House in the late 1930s for Eisner-Iger studios. But I believe Cave Girl could beat Sheena in a one-on-one comic character cat fight. After all, in “Altar of the Axe” Cave Girl is able to defeat a bevy of elephant riding Amazons!
Cave Girls popularity has led to several reprints in the 80’s and 90’s.
