This is a photo from 1976 of the Waldemarstrasse in Berlin. The wall was still white because they had just rebuild it. A few years later it was full with the typical wall paintings. This Flickr set shows you an artist in action a little further down the street.
I’m currently living in that street but I’ll soon move to a new place exactly between those 2 white walls. Weird.
