This volume is a collection of his early pre-Comics Code 50's work for Charlton Comics whose publishers were solely concerned about product not quality. Mostly horror, it also includes crime, western, SF, and romance. The Ditko style is already in place albeit not quite so initially defined as his work would later become, though it does evolve in the course of this volume. While I wouldn't recommended it as a Ditko-starter pack, there is more than enough to satisfy fans of his work who will find it a real treat. The horror stories are often gleefully grotesque. A couple of the more effective ones are gruesome reworkings of Cinderella (with vampires) and Rumpelstiltskin (a skin-collecting demon).
It's a nice, quirky book to have in your graphic story collection and I'll certainly be buying the second volume when it comes out later this year.
