 In June 1926, Lissitzky left the country again, this time for a brief stay in Germany and the Netherlands. There he designed an exhibition room for the Internationale Kunstausstellung art show in Dresden and the Raum Konstruktive Kunst (Room for constructivist art) and Abstraktes Kabinett shows in Hanover, and perfected the 1925 Wolkenbügel concept in collaboration with Mart Stam. In his autobiography (written in June 1941, and later edited and released by his wife), Lissitzky wrote, "1926. My most important work as an artist begins: the creation of exhibitions."
