Photos of Berlin in the 1920s

Here, some photos of (for me) unknown author, all with the same theme, in different aspects: everyday life in Weimar Berlin. There are dancers, there are soldiers, there are street vendors. There are even some glad members of the NSDAP. What that is? Nationalsozialistische Deutsche Arbeiterpartei. The Nazis.  I'm sorry for that, but in a photo reportage from the Berlin of those years, they are impossible to avoid.
