Rear tenements in Berlin
1922, oil on canvas, 60 x 41.5 cm, Österreichische Galerie, Vienna

Here are dilapidated houses and smashed fire walls abandoned to decay. This is the regression of man's work to the state of nature - the old theme of painting ruins, but seen here from a completely new, unromantic angle. The social aspect of this picture also plays an important role, representing the poor living conditions of the lower classes at the time.
