Henryk Strażewski was an outstanding art figure and faithful to the avant-garde from it’s birth in Poland in 1917 to his death in 1988. Constructivism had a strong position among others thanks to Strażewski, one of the main creators of this direction, who believed that art should be objective and rely on non-judgmental relations. Stażewski left behind a rich and mature collection of art that contains homogeneity and consistency. 24 pieces on display are accompanied by drawings and sketches. Stażewski sketched on pieces of paper and cartons, which indicate the immense work he put into the creation of his artwork.
