Man at the Crossroads (1934) was a fresco by Diego Rivera in New York City's Rockefeller Center. It was originally slated to be installed in the lobby of 30 Rockefeller Plaza, the main building of the center. "Man at the Crossroads" showed the aspects of contemporary social and scientific culture. As originally installed, it was a three-paneled artwork. A central panel depicted a worker controlling machinery. The central panel was flanked by two other panels, The Frontier of Ethical Evolution and The Frontier of Material Development, which respectively represented socialism and capitalism.
