Issued in 1981, this Austrian commemorative stamp celebrates the 75th anniversary of the Grazer Südostmesse (1906–1981), a major trade fair held in Graz, the capital of Styria. The design, by F. Krainz, features a stylized compass rose and industrial cog symbolizing innovation, trade, and regional connectivity. The central emblem incorporates the Messe tower, a recognizable landmark of the fair. Bold red and gold colors emphasize the festivity and economic importance of the event. This S4-denominated stamp is a striking piece for collectors interested in industrial heritage and Austrian exhibitions.
