The Smithsonian has commissioned a portrait made out of sand and soil that will stretch over six acres at the National Mall. Cuban American urban artist Jorge Rodríguez-Gerada, known for his large-scale “facescapes,” will do the work. The piece is a composite portrait of several people photographed in Washington and is called Out of Many, One, the English translation of the Latin E pluribus unum, which is on the seal of the United States. The piece will go between the World War II and Lincoln memorials. The work is expected to start in September. The finished product is expected to take 2,000 tons of sand and 800 tons of soil and be on view during October.
