Here is an exciting image of Turok Son of Stone from a Mexican version of the comic. The cover art is very dynamic and very very reminiscent of a classic Frank Frazetta image used as the cover for a Thongor novel.
Further the flying "honkers" behind Turok seem to be Mahars lifted from Frazetta's cover art for the novel Pelucidar.
As always, it's best to swipe from the very best.
This Turok cover while less a direct swipe, seems clearly inspired by another Frazetta piece used for the cover in Ace's Pellucidar series.
