Rudolf Wacker (1893–1939) is considered one of the most intriguing painters in Austria during the interwar period. Based in Bregenz in Vorarlberg, the westernmost province of Austria, he strongly oriented himself to the German art world. In his landscapes, portraits and still lifes, he analysed his close surroundings and the local reality in Austria utilizing a razor-sharp realism. As a prisoner of war in Siberia from 1915 to 1920, however, he also experienced ‘exotic’ worlds, which influenced his paintings throughout his whole career, not least in the form of memorabilia and souvenirs. The portrait of his wife Ilse (1926) reveals an important example of this phenomenon in the 1920s.
