From the beginning of the [Sovjet] Revolution I was a member of the Committee for Art. Was commissioned for the first Soviet flag for the First of May 1918, which was carried across Red Square by members of the government. Later I worked at 'Izo Narkomprosa'. From 1919 I taught at the Higher Artists' Workshops in Vitebsk [the 'Vitebsk Higher Institute of Art' - Lissitsky and Kazimir Malevich were invited to teach art by the director then Marc Chagall] (our students Suetin, Judin and others).
