Wow! JoJo's work is amazing on its own and an incredible tribute to his artistic mother, as well.
I believe either Gracie or Pat Hearn handled a lot of Greer's work at the time, in addition to Paul's store, Rose.
I own a small ink and watercolor painting by Greer that is one of my absolute treasures. And one of her few forays into two-dimensional expression. She was a true visionary.
