I stumbled across this blog on the Daily What, which has photos by a street photographer named Vivian Maier. She was a nanny in Chicago in the 50s and 60s. They were discovered in a box by a man named John Maloof.
I have to say, her work is absolutely fantastic and breathtaking! I'm not sure that even begins to cover it.
Golly, if only I could take photography like that...
