Issued in 1976, this 3 schilling Austrian commemorative stamp celebrates the 25th anniversary of the Österreichische Holzmesse (Austrian Wood Fair) held in Klagenfurt. Designed by A. Exax, the stamp features a striking geometric motif in red and orange, symbolizing wooden structures and the woodworking industry’s innovation. The background includes subtle outlines of gears, leaves, and pinecones—representing the harmony between technology and nature in Austria’s forestry sector. A modernist design, it reflects Austria’s strong industrial and ecological identity of the 1970s.
