The collection includes articles by domestic and foreign art historians devoted to previously unexplored aspects of the work of two prominent Russian artists. The creativity of artists is considered in the broad context of the art of the Russian avant-garde - not only the visual, but also the art of the theater. The vast majority of works, facts and events are analyzed for the first time. A significant part of the collection is made up of publications from the archives of N. Goncharova and M. Larionov, I. Zdanevich, N. Vinogradov and others.
