But Klutsis and Kulagina are primarily known for their photomontages. The names of some of their best posters, such as "Electrification of the whole country" (1920), "There can be no revolutionary movement without a revolutionary theory" (1927), and "Field shock workers into the fight for the socialist reconstruction" (1932), belied the fresh, powerful, and sometimes eerie images. For economy they often posed for, and inserted themselves into, these images, disguised as shock workers or peasants. Their dynamic compositions, distortions of scale and space, angled viewpoints and colliding perspectives make them perpetually modern.
