I’m trying to get ready to start the second summer term, so this is going to be short. But I wanted to point out that today was Roy G. Krenkel’s 98th birthday. Krenkel is best remembered today for his work with early comics giants such as Al Williamson and paperback covers for Ace, DAW, and Lancer.
Krenkel was a friend of Frank Frazetta, of whom Frazetta said, “I met Roy Krenkel back in 1949 or 1950, and he has never ceased to be a constant source of inspiration to me—a truly conscientious artist who will not tolerate incompetence.”
Much of Krenkel’s best remembered work was for fantasy adventure, particularly Edgar Rice Burroughs and Robert E. Howard. Edgar Rice Burroughs grandson Danton Burroughs considered him to be one of the great ERB illustrators. 
This was my education and my fondest memories.
That Kull cover is one of my favorite S&S covers hands down.
Guys, the more I see Krenkel’s work, the greater I appreciate it. I really wasn’t aware of him until I had been around a while. I’d seen his covers (and have quite a few). I liked his work, but it just took me a long time to realize what a body of work he had.
