Saul Leiter is an American photographer, known for his striking color photography of New York in the 1940's and 50's. They are really incredible, and I will be certain to present them one day soon, but today I want to take a look at his equally fantastic sketchbooks, which he shared with This Long Century. A major retrospective of Leiter’s work will be on show at Hamburg’s Deichtorhallen Museum, from February 2 — April 22, 2012.
