To mark the De Stijl centenary, which is being celebrated under the theme 100 years of De Stijl. From Mondriaan to Dutch Design, PostNL has joined forces with Het Nieuwe Instituut and The Gemeentemuseum in The Hague to produce a set of ten postage stamps. The De Stijl stamps bear images of masterpieces from both museums’ collections. This summer’s ‘pop-in expo’ at Het Nieuwe Instituut will show the context in which this stamp collection, designed by PutGootink designers, was made. The exhibition contains a film about the process of making the stamps, a masterpiece from the Theo van Doesburg collection, and a contemporary wallpaper design inspired by De Stijl.
