However, the couple does not want the exhibition to be defined as ‘the collector’s choice’. For that reason, Oxenaar asks Rudi Fuchs, at that time working as a research assistant in the print room at Leiden University, to develop the exhibition concept. Functies van tekenen devotes attention to contemporary artists’ renewed interest in this medium. The drawing is no longer an unfinished product, but enters the domain of conceptual art as a ‘document of mental activity’. The exhibition shows which functions a drawing may have, depending on the different motives of the artist to make the drawing. Fuchs distinguishes four categories – drawing as an explanation, as a definition, as a ritual, or as an exploration – and divides the participating artists accordingly.
