American realism

McSorley’s Bar (1912), John Sloan
Wikipedia - "American realism was an early 20th century idea in art, music and literature that showed through these different types of work, reflections of the time period. Whether it was a cultural portrayal, or a scenic view of downtown New York City, these images and works of literature, music and painting depicted a contemporary view of what was happening; an attempt at defining what was real. In America at the beginning of the 20th century a new generation of painters, writers and journalists were coming of age."
