I can't let this Howl-o-ween season go by without mentioning how much I loved the early issues of Creepy and Eerie.
I was aware of Frank Frazetta from his first run of Edgar Rice Burroughs Ace paperback book covers he had done in the early 1960's; but it seemed that he began to experiment and mature his painting style with his covers for the Warren magazines. Frazetta said that when he began retaining the original art, he did better work.
I remember being pleased and surprised with Gray Morrow's cover. I wasn't aware that anyone else, besides Frazetta, could paint. Morrow's style is not as fluid as Frazetta's; but I enjoyed the more finished rendering in the background as a contrast to Frazetta's looser impressionistic paint application.
