Here is the cover to STRANGE TALES #93. Despite the obvious hand of Ditko on this one, I never liked this cover. I never liked it even when I first saw it when I was a kid of about seven years old. It's just terribly bland and was not at all like the dynamic covers generally produced for these monster books by Jack Kirby and Steve Ditko.
I'm not even sure of the authorship of the art. Ditko definitely did the finishes, but it could have been over Kirby layouts, or pencils by Dick Ayers, or Paul Reinman. It's very hard to say. It just doesn't look like something Ditko would have concocted on his own unless he was rushed by a looming deadline or instructed specifically to create such an image.
|Ditko inks, for sure. But pencils could have been by any of the guys at Marvel then, up to and including Ditko. One of the most lackluster covers from this period at Marvel.|
