I just found this blog and I'm completely intrigued by the story....thousands and thousands of photographs (many only now being developed) taken by a very private woman, and only now being discovered. Spanning decades, most of the photographs were taken in Chicago and are "street photography," of ordinary and not so ordinary people and places and daily happenings.
The owner/discoverer of Vivian Maier's work is currently working on a book and documentary.
Check out the AMAZING photos on the blog. I'm looking through them now (and really, really hoping to find a photo of my grandma, grandpa, or mom who were all in Chicago during some of the years Ms. Maier was photographing in the city...wouldn't that be awesome?!)
