Cavemen Com'n Atcha by Frank Frazetta

Yeah, yeah, my own title for Neanderthal, but how boring is that?  First image is from the incredible second edition of Icon (first edition  sucked in comparison), second image is Betty Ballantine's publishing from the World Beaters posters (why everyone had a green forehead is anyone's guess, but I suspect Swine Flu, since it's from  the seventies), third image is the actual cover (mineminemineohyeahbaby), fourth image is a regulation cover, and the last is a color enhancement(seriously? I dig the cover)
