At 5:00 P.M. on May 9, 2019, I emerged from behind a paper curtain in a small room in Broad Art Center at U.C.L.A. and addressed the crowd gathered outside. I told them that behind the curtain were fifty items that cost me a total of fifty dollars, but the items wildly ranged in value. Each customer gave me one dollar bill, which I took behind the curtain and then returned with their item.
