The dust jacket on this book has lots of wear on the edges, but the centers of both sides are good and a dark blue. The dust jacket is now in a Mylar protector. 
The binding is tight and the boards are securely attached. The pages are really fresh as they spring back quickly when you fan them. They are fairly white and unmarked. 
Also, inside was a nice surprise. It was from when this was a brand-new book. It is the original receipt for this book that Joe ought back on January 3rd, 1977, and I don't think the book has been used much since, but the dust jacket has a lot of wear from storage. I have taken a pic and scanned it also for you at the end of the pics above.
This is a really nice copy which has a dj which is in not the best shape, but in a Mylar protector so it won't get any worse.  Also, the pages that are still fairly white along with a tight binding and good boards on the outside.
