The permanent exhibition is dedicated to the print work of Günter Fruhtrunk (1923-1982), one of the most influential geometric-abstract artists of the 20th century. He created a dynamic formal language with vector-like, diagonal lines whose alternating colors are rhythmically arranged, thus transforming the basic idea of Constructivism into a colorful world of images. The works of the Op-Art artist still possess a modern, contemporary aesthetic. An impressive selection of Fruhtrunk serigraphs is offered in the new exhibition rooms.
