The idea to create a catalog Heinzel came from the building which is dominated by blue glass. So we decided to take advantage of cover material that most resembles the glass, and it’s plexiglass. Papers (pages in the catalog) are connected with plexiglass by ordinary screws and nut. Because of this kind of connection we get the possibility of flipping pages for 360 degrees. Format of catalog is also reminiscent of the building which is shaped as a cube.
