Magick in Theory and Practice
Maroon cloth with gilt title on spine.
Crowley’s magnum opus, owned, signed, and annotated by Jack Parsons (1914-1952). Parsons was one of the founders of both the Jet Propulsion Laboratory (JPL) and the Aerojet Engineering Corporation. In recognition of his achievements, a crater on the moon was named after Parsons in 1972. His annotations in the book make it clear that he was using this book during the performance of rituals.
