Ostensibly it is factually true that each book was like the other and yet I felt that each had its own identity. In each book there is one host and his or her story anchors the book, while the others are guests in the book. Maybe not to the degree that Joe Orlando's DC books played up this reality, but still that's the feeling I get. THE HAUNT OF FEAR stands out because it's anchored by "Ghastly" Ingels' work on the Old Witch stories. Each artist gave a different tone to the stories, so THE HAUNT OF FEAR seems to be more in the category of gore.
TALES FROM THE CRYPT is a great title for a comic book (or a movie or a TV show) and that sets it apart. The Crypt Keeper is a better name for a host than the Old Witch or the Vault Keeper. That book feels like it's the leader, the top book. I read it as the more subversive book--critiquing the bland 1950s society that hides their skeletons in closets. I associate Jack Davis with this title.
THE VAULT OF HORROR feels like it has to take a back seat to the TALES FROM THE CRYPT. it's just not quite that special. And Johnny Craig, while a good artist, doesn't stand out. It's a sleeper kind of title. I associate the Vault Keeper's stories with those you might hear on old time radio--thrilling stories, but not over the top horror.
Another 1950s publisher of horror that many may not have heard of was Superior Comics in Canada. They were the Canadian publisher for the EC titles, but they did briefly publish their own line of horror comics that were sometimes nearly as good as EC. You can read more about them on my blog,
