For two years Richard Howe systematically photographed every street corner in NYC.
From his site:
The Manhattan Street Corners is my working title for a project to produce a comprehensive photographic portrait of everyday life at street level in daytime Manhattan. Between March and November, 2006, I systematically photographed each and every one of the island’s roughly 11,000 street corners (the exact number is a matter of definition and, in some ambiguous instances, even a matter of judgment).
