Lunch Atop a Skyscraper is a life-size recreation by NY-based Sculptor Sergio Furnari of the famous photo by taken by Charles C. Ebbets in 1932. The original photo shows a group of 11 construction workers eating lunch on a crossbeam during the construction of the RCA Building (renamed the GE Building in 1988) at Rockefeller Center in NYC. The sculpture was completed in 2001 and spent five months (from May to October, 2002) on display at Ground Zero before going on tour. It moves around quite a bit, apparently, but currently the statue can be seen on the corner of 45th Street and Broadway in Manhattan.
Note: The Statue is No Longer at this Address
