Looking at this amazon.com page, the seller writeroftruth states in their description "1st printing 1969". I'd wait for further comfirmation but it looks like the book was first published in 1969. Given Fischers age at the time, the year sounds about right.

Thanks for the information that later editions may have been different from the first (few?) printings. I do not have the book but I will keep the information in mind should I decide to get it in the future.
