This play, by Futurist poet Bruno Jasienski, is an outstanding example of the joining of left-wing politics and avant-garde interest in human mechanization that characterized the experimental theatre of Poland in the inter-war years. Stalinism and the purges cut short Jasienski's career and prevented productions of his play for many years - except for a brilliant constructivist staging in Prague in 1933. The Mannequins' Ball can now take its place along with Capek's R.U.R. as one of the major twentieth-century dramas making use of the themes and techniques of human automata. Reproduced in this volume are the eight woodcuts by Moor which accompanied the original Moscow publication in 1931.
