That's 100% right.
"Soviet posters first appeared during the Proletarian Revolution in Russia - they delivered Communist Party's slogans to the masses and called on workers and peasants to fight for freedom and justice.
Most of us are familiar with Dmitry Moor's famous poster "Have You Enlisted In the Army?" The image of a Red Army soldier with plumes of black smoke rising from the factory smokestacks in the background, bluntly questioning the Russian worker about his contribution to the defense of the October Revolution, became the iconic piece of Soviet propaganda. Posters took on a very important role during the October Revolution and subsequent Civil War. Very few newspapers were published in those days and often a poster replaced the tabloid. Poster art was widely accessible to the masses, the images it depicted were easily understood by everyone, and a short and energetic accompanying slogan stuck in the viewers mind, as a constant call for action. In time of Civil War, propaganda posters were sent to the front lines in the same capacity as bullets and artillery shells. They were posted on walls, in cities which were under assault by the White Guard armies and foreign interventionists. The bottom of the vivid, bright-colored poster usually contained a warning: "Anyone who tears down or covers up this poster – is committing a counter-revolutionary act". The poster was a powerful weapon, and just like any weapon, it had to be guarded with utmost care. "
