Beat the Whites with the Red Wedge
From The Art and Popular Culture Encyclopedia
Beat the Whites with the Red Wedge is a 1919 lithographic Soviet propaganda poster by artist El Lissitzky. 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.
A similar simplified version (rotated 1/4 turn clockwise) was appropriated by the German post-punk band Mekanik Destruktiw Komandoh (MDK) for their 1983 12" single Berlin, released on the sixth international label.
