I don’t have a lot of paperbacks with cover art by Frank Frazetta, but here are a few I do have…
Rogue Roman is an early cover painting by Frazetta that someone out there might enjoy seeing in its original format. The painting sans text appears in the Frazetta art book, Icon (Grass Valley, CA: Underwood Books, 1998), page 126. Looks a lot different there, too: the overall tone is much, much warmer. But I can’t decide if Rogue Roman is one of those pieces that was altered at a later date by Frazetta or not. And since there’s no mention of alterations in the discussion that accompanies the painting in Icon, it might just be a case of inaccurate reproduction on the paperback. Wouldn’t be the first time.
Of course, most Frazetta fans know that what makes the artist’s Moon Maid cover more than just a visually arresting illustration is that the original painting was substantially altered (though not, IMHO, improved) by Frazetta when he got it back from the publisher; which is to say, the painting as you see it here no longer exists.
The male model for The Mucker could easily have been Frazetta himself.
And finally, the central figure in Frazetta’s Tanar of Pellucidar was clearly swiped by Arthur Suydam for the painting that appears on the cover of his The Art of the Barbarian (Special Edition): Conan, Tarzan, Death Dealer. Look it up and you’ll see!
