WORLD WAR II ESTONIA

1941 Complete Mint Set of 6

Only 22 years after declaring its independence in 1918, Estonia was annexed by the Soviet Union in 1940 following a secret non-aggression pact with Germany. A year later Germany occupied Estonia as part of its invasion of the Soviet Union. A handful of stamps were issued during the occupation including this interesting set showing Estonian architecture to raise funds for Estonia's rebuilding program. (Estonia #NB1-6)
