There is a MADI museum in Dallas that had the outside of the building covered with Volf Roitman's work. Then one day, the work disappeared. I wondered what happened to this whimsical art piece. Sometime later, I moved to Jefferson, TX. I was driving around in the city of Marshall, TX which is a short drive from Jefferson. There near the downtown square was the MADI wall on the side of another building. Here is their Facebook page.
