I first encountered the work of Jeffrey Jones in the strip titled Idyl in the National Lampoon. It was like hearing Scott Joplin playing the piano in a bordello.
Here is the artist's site. Here is a retrospective appreciation.
Frazetta called Jones "the greatest living painter". There was a visible Frazetta influence in the early work, but there was a lot more going on. There were passages that reminded me of Whistler, N. C. Wyeth, John Williams Waterhouse and Alma-Tadema.
