Lunch atop a Skyscraper is a black-and-white photograph taken on September 20, 1932, of eleven ironworkers sitting on a steel beam 850 feet (260 m) above the ground on the sixty-ninth floor of the RCA Building (30 Rockefeller Plaza), then nearing completion, at Rockefeller Center in Manhattan, New York City. It was arranged as a publicity stunt, part of a campaign promoting the skyscraper. The photograph was first published in October 1932, during the construction of Rockefeller Center.Photograph credit: unknown, possibly Charles Clyde Ebbets
