This pair of Austrian commemorative stamps, issued in 1989, celebrates two major milestones in history and culture. The 6 schilling stamp marks the 100th anniversary of the Inter-Parliamentary Union (1889–1989), featuring Vienna’s Austrian Parliament Building and the iconic Pallas Athena Fountain, symbolizing wisdom and democracy. The 5 schilling stamp honors 900 years of the Benedictine Abbey of Melk (1089–1989), depicting the majestic abbey above the Danube, accompanied by allegorical figures and cherubs representing faith and learning. Both issues showcase Austria’s deep respect for governance, heritage, and artistic grandeur.
