Issued by Austria, this 1964 commemorative celebrates Tag der Briefmarke (Stamp Day) and features the picturesque Postautobahnhof St. Gilgen set against an Alpine lake and mountain backdrop. The design highlights Austria’s iconic yellow postal buses, symbolizing reliable rural mail and passenger service. Fine engraved detailing captures the architecture, vehicles, and serene landscape around Wolfgangsee. The 3.70g denomination and wide panoramic format make it visually striking in an Alpine or transport-themed collection. A beautiful crossover piece for collectors of postal history, buses, and scenic European issues. Crisp examples are especially attractive in MNH condition.
