The stamps on these two First Day Covers were issued in 1947. The stamp on the Left in the upper FDC was commemorating The Peace Treaty in Paris, PAX 1947, namely the second year of Peace following WW II. It features Ilmarinen, the ploughman by Akseli Gallen-Kallela 1900. It was issued on 2.6.1947. The second stamp was also issued on 2.6.1947, but, commemorated the Finnish Athletic Festival 1947. Known locally as Suomen Suurkisat, which loosely translates as The Finnisg Games. The first one was held in 1947, it was part of the re-building effort after the Second World War.
Both these FDCs were kindly given to me by my dear friend Pia.
