Underground Post of Ukraine, Ukrainian Flag

Ukraine · 1960 · 50 (Shahy?)

This stamp features the national flag of Ukraine, a simple bicolor of blue over yellow, representing the sky over wheat fields. The design is minimalist, with the word 'Українська' (Ukrainian) inscribed, emphasizing national identity. These were not official government postage but rather labels produced by nationalist organizations abroad.

Issued in 1960 by the Underground Post of Ukraine (Підпільна Пошта України), an anti-Soviet nationalist organization in exile, these stamps were created to raise funds and awareness for Ukrainian independence during the Soviet era.
