This 3 Heller stamp from the Republic of Austria, issued in 1919, features a striking Art Nouveau design by Josef Renner. The central motif showcases the double-headed Austrian eagle holding a hammer and sickle, symbolizing unity between labor and agriculture in the newly formed republic after World War I. Printed in dark green, the intricate geometric patterns and stylized typography reflect early 20th-century Viennese artistic trends. A classic early post-Imperial issue, it’s highly regarded by collectors for its bold symbolism and elegant engraving.
