Many thanks for posting that link to the new view of the 1972 Arbus Retrospective. I was able to see the 1967 New Documents show at MOMA, and it changed the way I saw the world.
I had never seen that amazing contact sheet self-portrait made with the Contax D before. I suspect Arbus did not print it because it was misframed and poorly exposed, and she was such a perfectionist about printing, but maybe she just felt it revealed too much about herself.
