Frank Frazetta's first Lancer cover was not for Robert E. Howard's Conan, but for Reign of Wizardry a book written by the great Jack Williamson. This is a pretty powerful Frazetta image. Below are some studies he did in preparation for it.
Lancer reprinted the volume a few times, once under their "Magnum Eye" logo.
This is pretty powerful Frazetta. I've not seen the original print anywhere on the multitude of sites which feature Frazetta's work, so I'm assuming this painting has been lost somehow, but I'd be curious if anyone knows.
And was this an inspiration for Frazetta. I wonder.
