More from this particular issue of Sick magazine from October 1962. The first two parts are here and here.
No credit here. I'm going to say Bob Powell.
Leo Morey is the back cover and much bigger. You'll see it next week.
Jack Davis was originally meant to be the cover. You can tell because not only is it in color and the interior art usually didn't have a signature, but it's also similar to the cover they ended up using. I like this one better.
