Just a couple of sad words about Gjon Mili for those who are too young to remember him. Post WW2 he was considered one of the great innovators in the use of light and motion. He had a large commercial studio in NYC which burned down with all his stored negatives, and then he was hit by a taxi and suffered brain damage. I don't believe that he ever recovered enough to work again, and was pretty much disabled physically, mentally, and financially by the time he passed away. This is certainly an extraordinary photograph.
