In 2007 a box containing 30,000 rolls of undeveloped film, prints and negatives by an unknown photographer were auctioned off and purchased for $350. After seeing the images the buyer quickly purchased another box of the same, totaling over 100,000 negatives, images, audio tapes, interviews and undeveloped film. The photography was the work of a New York City nanny, Vivian Maier, who photographed prolifically for over forty years but never exhibited her work. Maiers photograph's have now been turned into a book and documentary titled "Finding Vivian Maier." The documentary looks fascinating- check it out!
