Lunch atop a Skyscraper [New York Construction Workers Lunching on a Crossbeam] is a famous black-and-white photograph taken by Charles C. Ebbets during construction of the RCA Building [renamed as the GE Building in 1986] at Rockefeller Center in New York City, United States.
The photograph depicts eleven men eating lunch, seated on a girder with their feet dangling hundreds of feet above the New York City streets. Ebbets took the photo on September 29, 1932 on the 69th floor of the RCA Building during the last months of construction, and it appeared in the New York Herald Tribune on October 2 in its Sunday photo supplement.
