The collection "Avant-Garde" is represented by works of "agitational" and Suprematist porcelain, created after the October Revolution of 1917. The first post-revolutionary years were marked by an unprecedented surge in agitation-mass art. Porcelain took a special place in the visual propaganda of the ideas of the revolution. The art policy of the Imprerial Porcelain Manufactury was an integral part of the Leninist plan for monumental propaganda with clearly delineated ideological and artistic principles in art. Porcelain broke out of the framework of palace interiors and spoke in the voice of the revolution. Agitational porcelain entered the history of Russian porcelain as the brightest page of avant-garde suprematist art headed by K. Malevich, who reflected in porcelain the main theses of his new art theory.
