This Austrian stamp, issued in 1979 with a denomination of 2.50 schillings, promotes energy conservation. The striking design by O. Stefferl features a lit matchstick with its flame artistically forming the letter "e", symbolizing energy. The German slogan "Spart Energie!" ("Save Energy!") is a call to mindful consumption during the global energy awareness era of the late 1970s. The modernist layout and vivid colors reflect the urgency and relevance of the message. A notable issue for collectors interested in environmental or thematic propaganda stamps.
