Despite the title, Black Cat Mystic was actually a sci-fi anthology...
...featuring the final work of the Simon & Kirby Studio!
NOTE: May be NSFW due to racial stereotypes common to the era.
Penciled, inked, and probably scripted by Jack Kirby, this tale from Harvey's Black Cat Mystic #59 (1957) is Jack's first look at what would become known as the "ancient astronauts" theory in the 1970s due to the interest generated by Erich von Daniken's Chariots of the Gods.
At the same time, Kirby himself would expand the concept into The Eternals, (originally-titled Return of the Gods), which is now one of the lynchpins of the Marvel Universe.
Kirby would present a variation of the theme a couple of years after "Great Stone Face" in Race for the Moon's "Face on Mars" as shown HERE.
Note: Kirby and Stan Lee did a variation of the concept at Marvel in the 1960s with The Inhumans, who were created by Kree scientists visiting Earth in prehistoric times and genetically-manipulating humans to draw out dormant abilities.
