The stamps for the 1970 editions were designed by Jan Slothouber and William Graatsma in collaboration with the Centre for Cubic Constructions (CCC) in Heerlen. Every stamp displays a different corner point of the same block, highlighting eight distinct corner points, with four chosen for their unique identities.
The Bauhaus approach to design emphasised simplicity, functionality, and the integration of modern technologies and materials. A century later, many of the principles taught at the school remain fundamental to contemporary design practices.
Katayama worked in several art and design disciplines from graphic design and sculpture to environmental works and sculpture. His design work features rhythms and patterns and has a resemblance to modern jazz and the studies of Josef Albers.
He designed stamps from around 1955 and in the book Karl Oskar Blase, Briefmarken-Design, Verlag für Philatelistische Literatur, 1981, he was described as one of the most influential stamp designers in Germany.
