Issued in 1993, this Austrian 6 schilling commemorative stamp honors the 100th birth anniversary of Rudolf Wacker (1893–1939), a noted Austrian painter of the New Objectivity (Neue Sachlichkeit) movement. The design reproduces his work Selbstbildnis mit Puppe ("Self-Portrait with Doll"), blending geometric abstraction with expressionist detail. The artwork reflects Wacker’s introspective style and fascination with symbolic still-life elements. Designed by M. Siegl and engraved by G. Schmirl, the stamp is a vibrant tribute to one of Austria’s foremost 20th-century modernists.
