Lewis is most famous for his black and white prints, mostly of night scenes of non tourist, real life street scenes of New York City. During the Depression, however, he was forced to leave the city for four years between 1932 and 1936 and move to Newtown, Connecticut. His work from this period includes a number of rural, night-time and winter scenes in this area and nearby Sandy Hook. When Lewis was able to return to the New York City in 1936, there was no longer a market interested in his work. He taught printmaking at the Art Students League of New York from 1944 until his retirement in 1952. Lewis died largely forgotten in 1962. Lewis's print, Shadow Dance, sold for $50,400 at the Scenes of the City: Prints, Drawings & Paintings of New York 1900–2000 auction in New York on October 2010, setting a record price for the artist at auction.
