Vienna. Galerie Würthle. Sheets loose as issued in original plain orange wrappers. Very slight toning to edges of sheets commensurate with age; a very good copy. Three text leaves printed on thin blue/grey paper, consisting of title page, list of exhibited works, and artist’s introduction. With six linear black-and-white lithograph plates + six original hand-colored collages (narrow vertical strips of 2 or 3 sections each). Arnulf Rainer is primarily regarded as a pioneer of the Austrian movement “art informel.” Influenced by the surrealist principle of écriture automatique, in the 1950s he developed his obsessive Übermalungen or overpainting. However, Rainer himself called the Übermalungen he made in the latter half of the 1950s a dialectic reaction to his previous Proportionen work (1953/54). This early period of Rainer’s œuvre, with its geometric study and obsession with orderly dimensions, has been somewhat overlooked. These proportional works were originally shown at one of Rainer’s first solo exhibitions, held at the Galerie Würthle in Vienna, September - October 1954. Exceedingly rare. Only one copy located at the Akademie der bildenden Künste Wien; no holdings in North America. [Ref.
