The Psychic Feats of Olof Jonsson by Brad Steiger, Introduction by David Techter. Hardcover first edition published by Prentice-Hall 1971. Good condition copy. Sad but obvious damage is a tear across the ‘A’ in ‘Feats’ and a light upward bend to front board. Otherwise unmarked and tight bound. A fascinating piece of occult history! ISBN: 0137320167
