The book features elaborate documentation of the FREE SOL LEWITT project, produced at the invitation of the Van Abbemuseum by Danish artist collective SUPERFLEX. SUPERFLEX organised the reproduction of an artwork by the American artist Sol LeWitt. A metal workshop was created in the Van Abbemuseum where copies were produced and distributed for free to the public. The copied work is ‘Untitled (wall structure), 1972 and was acquired by the Van Abbemuseum in 1977. Around the FREE SOL LEWITT installation, SUPERFLEX curated an exhibition ‘In-between Minimalisms’ with Minimal and Conceptual artworks from the collection that focus on seriality, repetition, production and action. This exhibition was co-curated by Daniel McClean and Christiane Berndes. The book also contains extensive photodocumentation of this exhibition, an interview with SUPERFLEX and texts by Christiane Berndes, Charles Esche and Daniel McClean.
