The covers to these Lee Falk Phantom novelizations are simply wonderful examples of paperback cover illustration. I'm 99.9% sure that these were painted (for the most part) by George Wilson- although I have been unable to verify that. Wilson was a prolific illustrator who also painted hundreds of covers for Gold Key comics. Oddly enough, Wilson's art profile never mentions his comic book work.
