Your literary knowledge surpasses mine like a runaway freight train surpasses a snail sitting by the side of the rail road..
To try to relate my book to your ken, I will quote as good as I can its publishing credentials.
"A Bantam Book / published by arrangement with Holt, Rinehart and Winston Inc.,"
"Bantam edition published September 1969"
It would be my presumption that it is the 6th printing, as there is a tier of printing dates listed, the 6th being the latest. To my surprise, there is no ISBN number, or Library Of Congress number to be found ( I aint Sherlock or Columbo). My book is in English (I can barely claim to be fluent in English

and it is my only language to speak of.) Hey, I made an unintentional pun!

I pray for the day when I am capable of the simple computer skills so as to scan the cover or take a photo of it and employ it in my post. The cover is a kind of bawdy montage of the face and bust of a glamorous blond woman, a view of a semi-nude brunette womans bare back, a front view of a youngish formally clothed man, and a front view of a mature mans face with half a human face and half a wolf head face.
I am just about give out for today. Will be back and share more my delighted discovery about the relation of a similarity between one of the best Eastwood films (just in my humble opinion) and a Nobel Prize book.
Best Regards
