NO PHOTOSHOP! I could also have titled this “Happy Accident 2”. This is a traditional double exposure that happened by accident.
Elvis was shot on a large screen, projection [ancient] TV. I had to take the color film out mid-roll to do a B/W assignment. I put the color back in + shot the steel support work in a window @ the Chicago Civic Ctr. [now the Cultural Ctr.]. Apparently, I was one frame off when I advanced the film again + got this perfect super imposed image.
