Everyone knows Lego. But before the Danish company conquered the international market there were hundreds of firms that from about 1880 onwards produced a variety of construction kits. The DAM has the unique opportunity to draw on the private collection of architectural construction kits by graphic designer Claus Krieger to realize an exhibition that will break through the “glass barrier” that typically divides exhibits (for conservational reasons) from the visitors. They will be able to play and develop new buildings at about eight play stations integrated centrally into the exhibition.
