When Willem Sandberg, the newly appointed director of Amsterdam’s Stedelijk Museum, held an exhibition in 1946 in honour of Piet Mondrian, he did something quite remarkable. He placed a Swiss cheese plant next to Mondrian’s paintings. For Sandberg, the aesthetic placement of a plant in the museum made a statement. No longer would the Stedelijk be an elite temple for art; rather, he wanted the public to become accustomed to contemporary art in a familiar, domestic environment. Artist Inge Meijer investigated the vanished and subsequently forgotten vegetation in the museum during the 1945–1983 period for this book, rendering its history once again visible.
