Wish I had seen this post earlier! I am writing an ongoing series of articles on the Overstreet Guide for the Heritage Auctions Comics Newsletter. The #2 HC is discussed here https://comics.ha.com/heritage-auctions-newsletter/comics-and-animation-news-family-guy-lou-fine-and-a-pedigree-collection.s?id=5604 . I traced six copies of the #2 HC, but I did not know about this one. I presume the same owner has had it since 1972? Gary Carter did a lot of research on the Guide in the Comic Book Marketplace in the 1990s, conducting surveys, etc. He also found six copies, but whether they are the same six I found is unknown. The book in this thread does not appear to be one of the six I found, but it may have been reported in Gary's surveys. On the other hand, it might be a previously unknown copy. It's possible there are 13 known survivors, if these citations all represent different books. I found three different varieties of the #2 HC, with different dates on the binding stamps and different arrangement of the text on the cover. This book is the same variety as the one from Bob Overstreet's collection. I thought this variety might be some kind of prototype, since I could only find one example and it belonged to Bob, but this second example sort of works against that theory. Every time a new copy surfaces we expand the knowledge base for this very rare and important issue. About the color, they are all navy blue, but they look black in certain lighting conditions. The number 3 hardbound has the same navy blue cover and I bought one on eBay that the consignor described as black and looked black in the picture. When it arrived, I was relieved to see it was the standard navy blue color. Congratulations on finding this rare and valuable issue! I know of one private sale of a NM copy that brought $3,500, but that is a high record price. Check out the Heritage article for more information on varieties, prices, and pictures of some other copies.
