Although this is a picture postcard exhibit, it incorporates a considerable amount of social philately and postal history. It traces the history of PPC use in Russia from its very beginnings up to shortly after WWII, the people who sent them and the various reasons for which the cards were sent. It specifically excludes exchange-club correspondence, as well as cards with messages in Russian and Esperanto.
