During my stay in Germany in 1922 I collaborated with the writer Ehrenburg, on the Magazine 'Veshch' (Gegenstand) [= Object] (first pro-Soviet edition). [I] Took part in organizing the First Russian Art Exhibition 1922-23 in Berlin and Amsterdam. My works were purchased by European and American collectors and museums. The museum in New York acquired a 'Proun' from the Soviet Exhibition. At this time, in 1923, I contracted pulmonary tuberculosis.
