The museum presents drawings by 13 American artists: Carl Andre, Christo, Walter De Maria, Mark Di Suvero, Dan Flavin, Michael Heizer, Donald Judd, Sol LeWitt, Robert Morris, Bruce Nauman, Claes Oldenburg, Richard Serra and Robert Smithson. A considerable number of the drawings come from the Visser collection. The collectors Martin and Mia Visser were early advocates of these American artists in the 1960s, when they were introduced in Europe.
