The Malik-Verlag was the left wing publishing house in Berlin founded by John Heartfield and his brother Wieland Herzfeld.
Heartfield and George Grosz plied their craft as art directors / designers. This series of covers (below) was created for Kleine revolutionäre Bibliothek (1920-1923) by Heartfield with illustrations by Grosz and others. The duo also worked for the satirical publications Die Pleite and Der Knüppel. From 1924 to 1933 Heartfield designed illustrations for AIZ (Arbeiter-Illustrierte-Zeitung), the Communist Party mouthpiece journal, where he introduced photomontage as a political weapon.
