I love the illustrations. A couple weeks ago I came across references to a book by George Smith (writing under the name Jan Hudson) called Those Sexy Saucer People. It was written in 1967 and described the Aura Rhanes story and other contactee accounts. I was developing a collection at the time, but somehow missed this one. It had interesting cover art, which is why my parents would not have approved - and why I will not post the illustration here. The cheapest copy I can now find is $250, which my wife won't approve for that reason - although the cover could also factor into it.
I can't remember the first book I had. At some point I had an original edition of Ruppelt's Report on Unidentified Flying Objects, NICAP's UFO Evidence, Fuller's book on the Hills, and a lot of others. Probably an Adamski book. I do not remember any with such great art.
At some point, while I was at school, my mother gave the books away to someone interested in the subject. She did something similar with my baseball card collection that went back long before I was born - I probably got a lot of the cards from someone else's mother. I can't really complain although I regretted it then and now. At the time, I believed more in the revolution than in flying objects. Now I am not so sure about either. I just wish I had gotten a copy of the saucer book and kept it hidden for the cover art.
