Americana refers to artifacts of the culture of the United States, the history and folklore resultant from its westward expansion. Examples of this culture include baseball, apple pie, Superman, the Diner, barbed wire, wagon trains, jazz, the music of Stephen Foster, George Gershwin's Rhapsody in Blue, the music of Aaron Copland (notably his Fanfare for the Common Man), and rockabilly; and American art, such as that of Frederic Remington, Grant Wood, and Norman Rockwell, all based on American folk art.
