I have been making prints with artist Michael Williams. At the entrance of his studio is this basketball court. I knew that years ago, besides working with Ken Noland, Michael also worked with sculptors Isaac Witkin, Willard Boepple and Tony Caro, or should I say Sir Anthony Caro. He also assisted Jules Olitski, when he made sculpture. My guess was that this was an Olitski. Yup, its an Olitski.
