It may look like a brick wall from a distance, but Thomas Schütte's Große Mauer (Large Wall), on view in the upcoming Art of Two Germanys/Cold War Cultures exhibition, is actually a grid of more than 1,000 paintings. Each wooden panel rests on two thin nails attached to the wall. Quite an installation. See how it was done here:
