A newly published book apparently. Only $27. The photographs are excellent, usually one camera per page. Due to size and cost limitations, they weren't able to include many cameras one might expect. For example, the Nikon F is there, but no F2 or F3. I would've preferred a book with twice the content at twice the price. Still, it's worth having. I'm showing the Table of Contents so you'll know what to expect. Sorry for blurry photos from my old steam-powered phone.
