Bruno Taut
In the years immediately after the War, Krayl was involved with the Arbeitsrat für Kunst, the November Group, the Glass Chain, and Der Ring, along with Walter Gropius, Bruno Taut, and other members of the Expressionist movement. Krayl's paintings and drawings from this period are richly imaginative and visionary, with titles like "Cosmic building," "Dream city," and "Light greetings from my star house."
