1975 Austrian Postage Stamp - 75th Anniversary of the Vienna Symphony Orchestra

This is a vertical, rectangular postage stamp issued by the Republic of Austria (REPUBLIK ÖSTERREICH) in 1975 to commemorate the 75th anniversary of the Vienna Symphony Orchestra (Wiener Symphoniker 1900-1975). The stamp features a central oval vignette executed in a deep blue intaglio/engraved style against a muted grey background. The artwork depicts a musician in classical or tunicked attire playing a cello, framed by organic floral and leaf motifs. The denomination 'S 2.50' (2.50 Austrian Schillings) is prominently displayed at the bottom of the oval. The stamp is meticulously detailed, showcasing high-quality line engraving. Small inscriptions at the bottom edge identify the designer 'O. STEFFERL' (Otto Stefferl) on the left, the date '1975' in the center, and the engraver 'M. LAURENT' (Maria Laurent) on the right. The physical condition appears excellent with crisp, intact perforations on all four sides. It is shown mounted behind a clear protective strip in a philatelic album. The printing exhibits the fine cross-hatching and pressure-depth characteristic of mid-20th-century Austrian state printing, which is highly regarded by philatelists for its artistic merit and craftsmanship.
