Copenhagen. 1932. Thanks to @laxbikeguy (James) on Twitter for the link. "Cyclists in hundreds - thousands (millions it seemed to our cameraman!) throng the City of Copenhagen." Wild how there was only 12 views on this film when I clicked on the link from James. Feels like archeology. :-) Here is Copenhagen in 1937. When I found this in 2011 there were only a dozen views or so. Glad it got out to a wider audience. Copenhagen in the 1950s.
Copenhagen in 1923.
