El Lissitzky – Beat the Whites With the Red Wedge

Beat The Whites With the Red Wedge
El Lissitzky, “Клином красным бей белых! [Beat The Whites With the Red Wedge!]” (1919-20)
This lithographic poster was likely inspired by Nikolai Kolli‘s plywood street sculpture erected in Revolution Square in Moscow in 1918, which depicted a white block fractured by a vertical red wedge.
