Lunch Atop A Skyscraper is a famous black-and-white photograph taken by Charles C. Ebbets.
The photos shows New York construction workers eating lunch on a crossbeam during construction of the RCA Building (renamed as the GE Building in 1986) at Rockefeller Center.
Rockefeller Center was under construction in 1932 when this photo was taken.
The workers casually have 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.
This photo appeared in the New York Herald Tribune a few days later.
It is now one of the most famous photographs in the world.
An artist named Mike (Flickr user Balakov) has created a really cool lego reconstruction of Lunch Atop A Skyscraper.
Mike says, "I do seem to take quite a lot of photographs of Lego."
Well, we don't know why you do it Mike, but we are happy you do!
