Cave girl was published by Magazine Enterprises in 1955. She appeared in her own short run comic as well as in Thun'da and in Africa. Quote from Thun'da 3

For she is The Cave Girl, whose lips speak the language of the beasts, and whose hands are strong and supple to uphold the Jungle Law!.

 Oh yeah! The two comics II do have her in she goes skinny dipping gets beaten, whipped, tied up, trapped in a net and of course saves the day. Lots of action. I love that one line where she judges the man based on his yelling but in her infinite compassion decides to save him anyway. Truly one of the great Jungle Girls. She has a monkey as a pet named Nikki who responds to everything with cheeka-cheeka. How racist is the first scan?   Another missing origin if there is one.
