Frazetta's most famous works were in oil, but his canvases were rarely seen in museums; instead his legacy was defined by barbarians and warlocks who reached out to readers from book covers on dime-store spinner racks. But as comic books and fantasy entertainment gained a wider audience in the 1970s and '80s, Frazetta became a brand name and his original artwork became a sensation. Last November, one of his pieces, a berserk battlefield image that graced a "Conan the Conqueror" paperback, sold for $1 million to a private collector.
Here's a vintage Comics Journal interview with the artist.
