Book excerpt: This groundbreaking work examines four avant-garde groups that emerged in Poland towards the end of World War I; the Poznan Expressionists, the Young Yiddish, the Formists, and the Futurists. It is the first extensive study to bring the four groups together, and in doing so it establishes interconnections between them, and discusses their work in light of socio-political and cultural currents in Poland and wider Europe in the interwar period.
