I so want this to be true and provable. If there are copies extant with good provenance they would be blue gold. When the original book came out it was gold to me as a young pioneer. They went out like hot cakes and the profit as a young eager pioneer was almost worth going out on the work for. I was then, a true believer.
I would love to see/hear first hand evidence that this dynamite was a product of the 1970s and not some later spoof.
The source here, Atlantis/Petra makes me sit up and take notice, you are the a massive portal for good stuff so thank you again. If you could give us some provenance without outing anyone, that would be great.
