Kirchheimer (*1931) from Saarbrücken, who fled from the Nazis, filmed the material for this first New York graffiti documentary in 1977. Accompanied by a jazz soundtrack, the camera follows subways painted with graffiti, for example by Lee (Quiñones, *1960) or Daze (Chris Ellis, *1962). Kirchheimer contrasts the illegal graffiti with huge, sometimes more provocative legal billboards.
