If you came into science fiction or fantasy in the mid-70s, there was no escaping Frank Frazetta’s art (esp. the Death Dealer… how many vans was that painted on?). To say that he had an influence on my youth would probably be an understatement. A number of my grade- and junior-high classmates were semi-talented Frazetta wanna-bes, and I envied their drawing skills mightily.
I can look at his work now and cringe at the sexist and racist tropes he employed – but to a pre-teen boy, his work seemed like my internal visions brought to light.
