@coluber2001,
She was commissioned to do a "Dawn of the Bicentennial" bqs relief for Philadelphia. When I was a kid in my teens , (late 60') was introduced to Nevelson when one of my later art teachers ,John Costigan, a social realist (kinda like Katte Kollwitz in stylistic ways) wanted to go see her and re kindle an "affair" (I think that was the reason) (Costigan ws in his early 70s).
She was quite irascible and was fond of dressing like a street person (which she was for a period of time).
Later , in the mid 80's, a friend who was a rare book dealer, found some of her works on paper (these were sketches of wood works she was playing with for th Philly Commision) I went with him up to NY and I met her again. My friend (the book guy) had already known her and had apparently also had an affair with her. She was quite a sprightly ole bird.
