Stamps have always been part of the collective memory. One ultimate patriotic moment for every Finnish person is the final scene from the movie 'The Unknown Soldier´, where the Finlandia hymn is playing in the background when the war was finally over. Jean Sibelius, the composer of this moving hymn, appeared on a stamp in 1945. See this stamp and the entire collection at the jubilee exhibition at the Post museum.
(Jean Sibelius (1865 – 1957), a Finnish composer of classical music and one of the most notable composers of the late 19th and early 20th centuries. His music played an important role in the formation of the Finnish national identity.)
