This book would make a good way to dip a toe in the water of Evans' earlier work. This is where Evans developed his head-on documentary style; he photograped 20s/30s America's unglamorous side, and found charm and grace amongst the mundane without ever getting sentimental.
On a practical level, the book is small-ish but it's just about big enough for the pictures to work. The main section of plates are printed single-sided, with no nasties like splitting across pages. It opens reasonably flat if you pull a bit, so you can enjoy the pictures without getting a band of reflected light where the page bends. Printing quality is OK: the pictures look like they're made from old prints which were good in their time; they don't quite have the finesse or punch you'd get with modern prints or negative scans.
Frankly, I think the title is misleading. It should be "Walker Evans, The Early Work". Most of the pictures here are from the period up to 1936 or so, i.e. the stuff that made his reputation. That's a shame because Evans is notable as an artist who didn't peak then fade, he kept on doing good work and exploring new avenues throughout his life. The introductory essay -- high-flown but illuminating reading -- makes much of this. And I've seen some very good post-1936 photos in exhibitions. His New York subway candids, his series of photos from moving trains, and his later colour pictures as a photographer-at-large for Fortune magazine are all a match for the run of this book. But you won't find them here.
Still, if you want a look at the pictures that made Walker Evans a major photographer, this is decent quality at a very good price. And there are some real stunners in here, a couple of the great photos of all time. But you'll be needing a few more books if you get hooked.
