Beat the Whites with the Red Wedge (Russian: Клином красным бей белых!, Klinom krasnym bey belykh!) is a 1919 lithographic Bolshevik propaganda poster by El Lissitzky. In the poster, the intrusive red wedge symbolizes the Bolsheviks, who are penetrating and defeating their opponents, the White movement, during the Russian Civil War.
The image gained popularity in the West upon Lissitzky's migration to Germany in 1921. It is considered symbolic of the Russian Civil War in Western publications, and is often used in album art and advertisements.
