Mysteries of the Unknown is a series of books about the paranormal, published by Time-Life Books from 1987 through 1991. Each book focused on a different topic, such as ghosts, UFOs, psychic powers and dreams. The series was very successful for Time-Life Books, and the idea was conceived following the popularity of their Enchanted World series of books (which I have a full set for sale, see my other actions.)

This set is in near-mint condition, with most showing minimal-no shelf wear, and about 3-4 of the Volumes showing light shelf wear. The Master Index shows light-moderate wear, but still good condition, as it's the most used book in the set.
