In 1919, Paul Citroen began his series of groundbreaking urban collages, of which the current example, Metropolis, 1923, is the best known. Initially affiliated with the Berlin Dadaists, Citroen studied at the Bauhaus in Weimar from 1922 to 1925. Metropolis was recognized early on as an important image and was reproduced extensively in the 1920s, most notably in László Moholy-Nagy’s seminal book, Painting, Photography, Film. This print bears the stamp of a Weimar photo studio indicating that it was made prior to Citroen’s return to Berlin in 1925. Another print of this image is in the Thomas Walther Collection at The Museum of Modern Art, New York.
