In 1972 they took part in the exhibit "Italy: The New Domestic Landscape" at New York's M.o.M.A. At the same time, through a host of installations they tested “borderline” creations standing between architecture and design, including installations for the exhibit "Italienische Möbel Design 1950/80" in Cologne.
In 1979 they received the Compasso d'Oro award. Their works are owned by the major museums worldwide. Their production is portrayed in histories of Italian design and in the main international publications of this field. Besides the design activity they also made a theoretical contribution through the Industrial Design Association. Mr. De Pas died in 1991.
