ROSTA windows (also known as ROSTA windows of satire or ROSTA posters, ru|Окна сатиры РОСТА, Окна РОСТА, ROSTA being an acronym for the Russian Telegraph Agency, the state news agency from 1918 to 1935) were a propagandistic medium of communication used in the Soviet Union to communicate important messages and instill specific beliefs and ideology within the minds of the masses.
Rosta posters were a highly popularized form of communication used by the Russian government during a short time period between 1919 - 1921. The posters were used to communicate mass messages and propaganda during the Russian Civil War. Once the war came to an end, the Russian government turned to new forms of communication.[1]
Rosta posters were easily identifiable by their context and distinct style.
The basis for the content of ROSTA posters was political messages from the Soviet Union, sometimes referred to as agitprop. Agitprop is political propaganda, especially the communist propaganda used in Soviet Russia, that is spread to the general public through popular media such as literature, plays, pamphlets, films, and other art forms with an explicitly political message.
