Issued by Vatican City during the Sede Vacante period of September 1978, this 200 Lire stamp commemorates the interregnum following the death of Pope Paul VI before the election of a new pontiff. The design features the traditional crossed Papal Keys beneath the umbraculum, symbolizing the temporary governance of the Holy See. Rendered in a stained-glass artistic style by E. Vangelli, the stamp reflects ecclesiastical authority during papal transition. Sede Vacante issues are highly collectible due to their limited issuance tied to specific historical moments. A significant thematic piece for Vatican, religion, and papal succession collections.
