Museum Boijmans Van Beuningen’s official Depot page dates a recreation of Wim T. Schippers’s Peanut Butter Floor from 9 July through 6 September 2026, using 390 kilos of Calvé peanut butter across a 25 m² hexagon. The museum frames it as a tribute after Schippers’s death; NOS and de Volkskrant reported he died in Amsterdam on 10 June 2026 at 83, with the foundation announcing days later. Depot ticket required. Spreading days were 2–3 July.
