The collection of Marguerite Arp-Hagenbach, widow of the sculptor Jean Arp, contains mainly constructivist and concrete art, with Jean and Sophie Täuber-Arp as central figures. According to Oxenaar, she began collecting ‘where Mrs Kröller left off, whereby her collection gives an indication of ‘how it could have been in Otterlo and partly how it became’. The exhibition can be seen ‘as an almost self-evident continuation of the existing collection in the museum’. After the exhibition, Marguerite Arp-Hagenbach presents the museum with a copy of Soleil recerclé, the last woodcut that Jean Arp completed before his death in 1966.
