Pride of the association has been its ability to link tradition and modernity in an executive functional synthesis to the transformation in mosaic or cartoons of painters and / or designers always safeguarding  the quality, using strictly artistic-craftmanlike techniques.
With regard to this we quote the useful collaborations with: Chagall, Guttuso, Campigli, Saetti, Vedova, Severini and many others.

Among the many artists who have approached the art of mosaic producing cartoons  for their transposition, it is important to quote Kokoschka (1974) and Sharir (1995).
Kokoschka's project, an oil "cartoon", size 1.40 X 2.10 m., portraying  the foreground of a crucified Christ, in pain with a soldier, giving him a sponge soaked in vinegar in order to protract  his agony, was given to the old church of S.Nicolai  in Hamburg, almost destroyed during the last war.
Kokoschka, in one of the most uneven period of his life, wanted to give a strong message reminding the sadness and the pain suffered in the universalism of Christ.
