"21-87 is a 1963 Canadian abstract film created by Arthur Lipsett that lasts 9 minutes and 33 seconds. The short film, produced by the National Film Board of Canada, is a collage of snippets from discarded footage found by Lipsett in the editing room of the National Film Board (where he was employed as an animator), combined with his own black and white 16mm footage which he shot on the streets of Montreal and New York City, among other locations."
