In autumn 2003 the head of the Aachen chapter's press office, Mr. Roland Wenzler, asked me to create a children's papercraft sheet of the cathedral for the Aachen Karlsverein. Among many other projects this was meant to financially support the restoration works of the cathedral. All individual parts of the paper model are placed on six A4 sheets which can easily be sent by post in their red envelope. Detailed instructions and a number of photographs are included, as is a solid piece of cardboard which can serve the young and old builders as a ground plate. The model is on sale for € 3,50 at the chapter, in the treasury and in the cathedral's gift shop. Besides the construction of geometries for the model I was also responsible for the complete graphic and editorial work for the project, including the graphic design of the model surface and the whole outline of the cover with all drawings, texts and photographies.
