Nighthawks (1942) by Edward Hopper is his most recognizable painting and one of the most famous in American art. Various artists have produced works that allude, parody or pay homage to it in literature, film, television, music and other paintings. It depicts four people in a diner late at night, as viewed from outside through a large glass window. Light from the diner illuminates a dark and deserted street. When asked about the lonely mood, Hopper responded that he "didn't see it as particularly lonely ... unconsciously, probably, I was painting the loneliness of a large city." Many have searched for the real diner, which either no longer exists, or never existed.
