It does look like him especially from his role in The Innocents and that even looks like Bly Manor in the background. As for reading it Bob no I never had that honour. It is a very Gothic cover though.thanks for posting. I did find this brief mention and while it does resemble Tomb of Ligeia I think that you are spot on with Peter as the model.
This cover for Dracula Began, a 1976 novel by Gail Kimberly, is stunning: you got Vincent Price from Tomb of Ligeia with misplaced eyes, big black bats, a Gothic castle, village people on the hunt, and a totally incongruous lady's head on a platter. Amazing. Artist George Ziel is a master of the vintage horror paperback cover!
