#28: The Exorcist – William Peter Blatty (Harper Collins, 1971 and beyond)
As a young child, this cover image ruined me. At 4 or 5 years old, I thought it was a real photograph of a real demon, and that if I stared at it too long, it would somehow come and find me. This landmark cover didn’t change much through the 1970s. But most likely, the publisher got too many complaints and obscured the image as you can see from below.
