75th Anniversary of the First Slovene Postage Stamps for the Slovene Littoral and Istria - Set

Immediately after the armistice that ended the First World War, the Italian army occupied Istria and the Slovene Littoral. Under the terms of the 1920 Treaty of Rapallo, these areas were assigned to the Kingdom of Italy. After the Second World War, when the Yugoslav and Allied military units that had liberated the Littoral (including the present-day Primorska region) divided the territory into two administrative zones, the Yugoslav side decided to introduce its own postage stamps in its territory, Zone B.
