On the occasion of the 60th birthday of Dutch sculptor André Volten in 1985, the Rijksmuseum Kröller-Müller organizes a solo exhibition with over 60 maquettes and models of his sculptures. These are, as Oxenaar describes, mainly ‘sculptures that are connected with architecture and with urban or rural situations’. Volten himself is responsible for the layout of the exhibition. Oxenaar and Hammacher both contribute to the catalogue, for which architect Wim Quist writes the introduction.
