This 2-franc violet stamp from Saar pays tribute to the Ludwigs-Gymnasium in Saarbrücken, one of the region’s historic educational institutions. Issued during the final years of the Saar Protectorate, the design presents a crisp architectural engraving showcasing the school’s modernist façade, complete with sculptural reliefs and clean geometric lines. The work of Mees (del.) and Dufresne (sc.), the engraving exemplifies Saar’s beautifully crafted definitive-style issues of the 1950s. A desirable piece for collectors of Saar postal history, architectural themes, or post-war European political territories.
