I'd been after it for years but every time I searched, the prices were in excess of $70. While on vacation, I found a very good copy in a used bookstore in Portland for $46 and thought "Hey, that's not a bad price" but before I purchased, I had one last look on Abebooks (I hadn't looked in a while) and found a copy of similar quality for $20 including postage. BARGAIN!!! It arrived a few days ago and I'm really glad I added it to my collection. The photo section in the middle of the book is fascinating enough in its own right.
Got a $30 Amazon gift card courtesy of a peer-to-peer award at work...and it paid for 75% of this wonderful book. Quality is top-notch and the pictures are superb. A "must have" for anyone interested in this period.
