The photo by Charles Ebbets showing workers having lunch high up on a transverse girder is one of the most celebrated in history. That photo was taken at the start of the 1920s while the Rockefeller Center was being built.
But it was always inevitable that, sooner or later, The Simpsons would create their corresponding parody of it, and this is precisely what is offered by this wallpaper. It shows The Simpson family on a girder, dressed as workers of the age, in black and white (as is the original image), while they have lunch and watch TV (which is on another parallel girder).
This Simpsons on a transverse girder wallpaper is only available in 1024x764 pixel size.
