Apparently she leaves a treasure of about 100,000 photos as a legacy to the world. Nobody knew she was taking pictures of the world around her. I like that she took pictures of people from all walks of life: the rich and the poor, the young and the old, the pretty and the ugly, men and women, children and elderly, black and white, they are all there on her negatives. Bit by bit the negatives are printed and published.
"Vivian Maier represents an extreme instance of posthumous discovery; of someone who exists mainly in terms of what she saw. not only was she entirely unknown to the photographic world, hardly anyone seemed to know that she even took pictures."
