Geometry and colour This collector‘s item is a replica of the historic cradle designed by Peter Keler in 1922 during his apprenticeship at the Bauhaus. The small cradle is congruent to the original in color, shape and proportions at a of scale 1:7, and to a large extent, is carefully hand crafted. The original cradle of that time can be seen in the Schloss-Museum Weimar, when it isn’t on tour with their worldwide exhibitions. Only since the late 1970s has the cradle been produced by the Tecta Company.
