As is often the case with Poor condition books, this one is in pretty good shape… EXCEPT… for the major spine crack and separation from the pages. See the photo. All pages are here, and they are in nice condition. Except for the two pages right at the crack the pages on either side of the crack are securely attached to each other, and partially attached to the cover. Looks like a serious case of failed glue. Still, this is a rather hard to find book with some very interesting information in it. With only 2 actual loose pages it still manages to read decently. Amazon lists it for over $50. Will anyone give us $20 for it?
