In 1929 Walter Georg Kostka presented this light cube designed for Atrax at the Internationale Reklameschau in Berlin. The cube was made of crystal-covered (double-walled) opal glass in a warm white tone. The Atrax cube was considered a new light component that adapted to modern architecture and spatial art.
