Abstract, geometric forms, became the basis for the most outstanding works of the avant-garde sculptor Katarzyna Kobro. With her 'Spatial Compositions', she created her own artistic language, with which she aroused a lot of criticism, which was based on the traditional assumption that a sculpture should be a compact, modelled mass. However, the task of "Composition" was to shape forms that were to come into being. Kobro, however, still wanted to change the space surrounding people with her own art.
