Beat the Whites with the Red Wedge ("Клином красным бей белых!") is a 1919 lithographic Soviet propaganda poster by artist Lazar Markovich Lissitzky, better known as El Lissitzky, "the man through whose exertions the new Russian ideas became generally understood in Western Europe". In the poster, the intrusive red wedge symbolises the bolsheviks, who are penetrating and defeating their opponents, the White movement, during the Russian Civil War. It is an example of Constructivism.
