This nice ad for Levi's Cling fits is from 2007 and was made by JWT Advertising Agency in Bangalore. The photographer was Steve Koh.
To me it looks like a quotation of the famous photo by Charles C. Ebbets "Lunchtime atop a Skyscraper" from 1932. Above all because I think that no photographer in the whole world can take a picture of a crossbeam with people on it without thinking of Ebbets.
