On May 15th I did a bicycle tour to the city of Leverkusen (just beyond the border of Cologne) and visited Museum Morsbroich there. There is currently an exhibition with works (woodcuts, collages, drawings, ceramics sculptures) of the Tobias brothers. Very interesting artists who always work together. Highly recommended. Also shown is an exhibition with wood cuts by different artists from the museum’s collections. If you happen to be in the Cologne/Leverkusen area, this museum is definitely worth a visit. See here for an article on this exhibition (in German, but you can see some of the pictures there).
