This 60 Heller red stamp from Austria (Österreich), issued in 1916, features the iconic portrait of Emperor Franz Joseph I riding on horseback, based on artwork by Koloman Moser, a leading figure of the Vienna Secession. Issued during the late phase of the Austro-Hungarian Empire, the design blends imperial symbolism with Secessionist decorative borders. Printed typographically, it belongs to the celebrated 1916 wartime definitive series portraying Franz Joseph in various military poses. Used examples like this one often show heavy cancellations, adding postal history value by marking the stamp’s circulation during World War I. A desirable piece for collectors of imperial Austria, military themes, or Secessionist design.
