Great portrait. She was the first person that came to mind, Bree, but I had forgotten the All About Eve connection. Thomas Gainsborough also did an oil on canvas of her that hangs in the National Gallery, London, but it's too large to post here. I remembered reading somewhere that she haunted one of the theatres in London.
I'll start a round, but I'm leaving in a half hour and won't be back for approximately another 3 hours if you care to set my round aside.
