Illuminated in fiery orange and red against a deep cobalt Viennese night, the Hochstrahlbrunnen fountain at Schwarzenbergplatz erupts in a theatrical display of colored light — behind it, the curved neoclassical façade of the Konzerthaus broods in silhouette, a scene that captures Vienna's postwar flair for spectacle. Rosemary, fresh from an enjoyable week in Italy (arriving by train), sent this dazzling night-view to a friend in Dayton, Ohio, noting wryly that Vienna had finally forced her to reach for her spring coat. The Austrian stamp commemorates the XV Universal Postal Union Congress held in Vienna in 1964, showing camel caravans crossing a desert — a philatelically significant issue pairing beautifully with a night-time chrome card full of color and drama. The Hochstrahlbrunnen dates to 1873; its nightly illumination became a postwar Vienna attraction celebrated on countless tourist cards of the era.
