1959 American National Exhibition in Moscow was the first introduction of the USA to Soviet people. It went with great success and was attended by millions of Soviet people. Who knows, may be it was the first nail hammered into the USSR coffin.
The U.S. used posters more than any other method of broadcasting propaganda, and produced more propaganda posters than any other country fighting in World War II. Almost 200,000 different designs were printed during the war.
