This photo montage, or "double" as Bill called them - literally two slides sandwiched together - includes a view looking up at a Manhattan skyscraper, taken in the early 1970s. The montage itself was used in various contexts in the 1970s, like this Harper's cover from March, 1980. I've been wondering, can anyone identify the building?
