Every large museum collection with a long history contains paintings, arts and crafts or curiosities that do not really belong there. Yet they have ever ended up in it: donated or by other means. A small selection of these objects was shown in the museum, such as a ‘Madonna’ by the Italian painter Sassoferrato (1609-1685), a 17th-century straw painting by Hendrik Pronk and prints by Pablo Picasso and Anton Pieck.
