November 02, 2011 8:24am I met Imogen Cunningham who did a very similar shot. It was about 40 years ago, and she was in her late 70s at least and died a couple of years later. She did this shot in Golden Gate Park for Judy Dater (another photographer and early feminist) You could look it up (Imogene encounters a Nymph).
This inspires me to do some similar works.
