Issued in 1979, this Austrian stamp with a face value of 2.50 Schilling promotes Gewässerschutz—the protection of waterways. The design by F. Dorner and A. Nefe contrasts two worlds: a serene, tree-lined stream in lush green tones on the left, and an industrial skyline rendered in violet on the right. This powerful imagery highlights the balance between industrial progress and environmental responsibility. A key piece in Austria’s environmental awareness series, it reflects the country’s growing ecological consciousness in the late 20th century.
