The lost works of Willem de Ridder (De verdwenen kunst van Willem de Ridder)

Amsterdam/Zaandam, Stedelijk Museum/Stichting Hai Nun, 2016. Complete edition including a documentary film by Frank Herrebout. Collection of ten works by Willem de Ridder, each comprising of a dvd and a multiple (paper constellation) in various formats, some framed, all signed and numbered. A complete list is added with the edition and available upon request. This is one of only 6 complete editions published.

The documentary features the Ridder's project that started in the 1980s in which he illegally placed artworks in the Stedelijk Museum. The Fluxus artist also organized a (clandestine) show at the Stedelijk in 1997 in which he guided visitors through the museum by audio tour (on walkmans) pointing out his artworks (such as thumbtacks and small decorations). After the major renovation of the museum (2004-2012) many of them were damaged or removed. An information leaflet about the film and a floor map locating the 'lost' works in the museum is added to the multiple.
