Das ist in der Tat ganz großes Kino. Das muss man unbedingt gesehen haben als Bewohner der Hansestadt. Gar keine Frage.

Hamburg – Great City on a Great River from Friedemann Wachsmuth on Vimeo.

It is the english version of “Hamburg mal ganz anders”, which played as supporting film for UA’s “Love Story” (1971). It was produced in 1969. This film exists with two different endings, this is the “cinema edition” (the other version ends with a helicopter scene)
I assume this was a quick and dirty pulled work copy, as it has weird cropping and some constant vertical color gradient in the frame center.
