Here is the extremely rare book by 1950's Contactee George Van Tassel.

Van Tassel was a classic 1950s contactee in the mold of George Adamski, Truman Bethurum, Orfeo Angelucci and many others. He hosted The Giant Rock Spacecraft Convention annually beside the Rock, from 1953 to 1978, that attracted at its peak in 1959 as many as 10,000 attendees. Guests trekked to the desert by car or landed airplanes on Van Tassel's small airstrip, grandly called Giant Rock Airport.^{[citation needed]}

Every famous contactee appeared personally at these conventions over the years, and many more not-so-famous ones. References often state that the first and most famous contactee, George Adamski, pointedly boycotted these conventions. In fact, however, Adamski attended the third convention, held in 1955, where he gave a 35-minute lecture and was interviewed by Edward J. Ruppelt, once head of the Air Force Project Blue Book. It was the only such convention Adamski attended.^{[citation needed]}

Like most 1950s contactees, he founded a paranormal research organization calledThe Ministry of Universal Wisdom, and The College of Universal Wisdom to codify the spiritual revelations he was now continually receiving via "psychic resonance" with the Space Brothers.^{[citation needed]}
