Two sizable photo books that have recently been heavily discounted but definitely don't have the depressing "remainder" aroma hanging over them:
Louis Stettner: Wisdom Cries Out in the Streets and
Soviets: Pictures from the End of the USSR. Only partially portraits, and the former even has some (gasp) color. Of course the latter is grim in places, but Oh The Humanity. No, really, it's great; and since it's a historical document as well as a collection of wonderful photographs it's particularly sad that it has been remaindered.
A bigger one is the recent monster collection of Edouard Boubat, published under different titles in the Youess and the Youkay.
Sorry, but I read the so-called "International Herald Tribune" on my way to work today, and the excesses in this paper for rich American francophobes stuck in my craw. So I'm feeling particularly francophile this morning. Yes,
Willy Ronis (and I'm sorry to give you an Amazon link but FNAC seems not to be working right now).
