I saw this recently and was just awed. Says so much about photography, about history, about her... and what was the photographer thinking, that this was just another disabled girl? Or that this photograph might one day be a priceless record?
It raises one issue for me, relating to a recent discussion of "truth" in photography. This is an example of a subject who likely would not have reacted to the presence of the photographer. A very different kind of human subject. In that sense, because she is rather vulnerable in this state, the photograph has a quite different meaning than found in most portraits.
