Ravens, by Masahisa Fukase

Why?

"I originally discovered the 1991 American edition of Fukase’s masterpiece in a Barnes and Noble sale bin. At the time, I didn’t know a thing about the book, nor was I impressed by the book’s design. But as I paged though the book, I immediately knew I was in the presence of a singular project. For me, Raven’s is the single best photographic sequence I’ve ever encountered."
