"The last pre-war Polish avant-garde" is how the group of young Kraków artists known collectively as the 'Kraków Group' is often referred to. Aleksander (Sasza) Blonder (pseudonym André Blondel), Blima (Berta) Grünberg, Maria Jarema, Franciszek Jaźwiecki, Leopold Lewicki, Adam Marczyński, Stanisław Osostowicz, Szymon Piasecki, Mojżesz Schwanenfeld, Bolesław Stawiński, Jonasz Stern, Eugeniusz Waniek, Henryk Wiciński and Aleksander Winnicki were passionate left-leaning rebels, uncompromised in their opposition to the existing academic art of that time, and artistically connected to Cubism, Futurism, Constructivism and Expressionism. The exhibition features about 300 works, both traditional as well as abstract, including drawings, graphics, sculptures and paintings.
