I've scoured the web for this one and am surprised as hell that no info is available. The photograph is of construction of the Waldorf--obviously in 1930--with two workers at some fine dining on a crossbeam high in the air. At their side are two well-dressed servers. Google "Waldorf, 1930" for a picture. Who's the author? Was it faked or real? If it was for a newspaper, which publication?
