Just took out my copy after seeing the tissue inside on the eBay item. Never knew it had one. Had to find it (up front). Amazing. And that book looks like the dog got hold of it. This book is a rare gem; I can't believe it's not the most valuable (or one of) Buk's books. In short, I perceive it to be art, more so than a book...I was the underbidder on the one on ebay recently:
