The Boijmans Van Beuningen Museum in Rotterdam, the Netherlands, has launched an exhibit that features a 270-square-foot hexagon made of peanut butter. And just for the record, it is smooth, not crunchy.

The whimsical artwork is in honor of Wim T. Schippers, a very much well-known artist who wrote poetry and music, produced TV shows, and even directed a play (in which the actors were dogs). He was very much referred to as eccentric, but he had many fans.

Schippers died in June 2026. One of his last requests was that the museum honor him with a Pindakaasvloer ("Peanut Butter Floor"). And other than his strict instruction to avoid crunchy peanut butter, Schippers specified that the artwork must use 3.2 pounds of the nutty spread for every square foot. (So doing the math, that's 864 pounds of peanut butter.)

Schippers even chose the brand, the Dutch manufacturer Calvé, which donated the more than 800 standard jars required to execute the artist's vision.

The artist mused about the data as early as the 1960s, but it wasn't until 1989 that he first saw his idea for real. The museum bought the concept and showed it off in 2011. That exhibition proved very popular, particularly with children. Both the artist and the museum were dismayed, however, when a few visitors accidentally walked on the exhibit. (This has already happened again, in 2026.)

Schippers (left) was born in Groningen in July 1942, in what was then German-occupied the Netherlands. He studied at an Amsterdam arts academy and embarked on a career as a visual artist.

He became well-known to TV audiences when he provided the voicing for Ernie, Kermit the Frog, and Count von Count for Sesamstraat, the Dutch version of Sesame Street. He and Paul Haenen, who voiced Bert, collaborated on a number of Bert and Ernie albums. Schippers also voiced Happy in the Dutch-language Snow White and the Seven Dwarfs rerelease, in 1984.

But it was his sense of humor that caught the attention of many. Once on live TV, he poured a bottle of lemonade in the North Sea. In 1965, he published a full-page article delineating the different types of meat balls.

A success in writing, music, television, and visual arts, Schippers was awarded the Jacobus van Looy prize in 2005.
