Artigas had to work from an image which Miró had created at one-tenth the scale of the finished wall.
The artwork was completed in 1979 and includes the signatures of both artists at the bottom, left-hand corner.
Artigas junior worked with Miró for twenty years creating other similar sized murals for UNESCO, IBM and the Palacio de Exposiciones y Congresos in Madrid.
After that, the tiles were transported by lorry and train to complete the journey from Catalonia (Spain) to south western Germany.
