As for the Joan Mitchell influence, I should also disclose that I have a special relationship with her. When visiting SFMOMA with my energetic five year old, I found a magnificent Joan Mitchell painting, "Bracket". It is very large, a good ten feet high and wide, and valued somewhere near $5 million. As I examined the painting from afar, my five year old fell right into the painting - because of it's size it nearly reached the floor. Luckily the canvas didn't rip and the astonished museum guard simply watched as I scolded my son and let him play with my i phone for the rest of the visit.
