The museum also owns 26 graphics by Pablo Picasso from the 1940s and '50s, plus others by Joan Miró, Marc Chagall and Salvador Dalí.
In the early 1990s the museum acquired over 1,000 works from the collection of the artist Siegfried Cremer, by artists including Marcel Duchamp, Joseph Beuys, Nam June Paik, Wolf Vostell, Günther Uecker and Jean Tinguely, strengthening the museum's coverage of the Fluxus, ZERO and "informal art" movements.
