Wim T. Schippers’ peanut butter floor will return to the Boijmans van Beuningen Museum in Rotterdam next month as a tribute to its creator, who passed away last week at the age of 83. The museum considers it a fitting way to honor the artist and voice actor.Schippers considered art just as nonsensical as life itself, the museum said. It doesn’t have to make sense, but it is always worthwhile.
