No, unfortunately I haven’t visited IMM Cologne in 2016, but I plan to do so again in 2017. Via Design Boom I found out that Patricia Urquiola had designed Cassina’s stand there (and later in Milan). It was in celebration of Cassina’s 90th Anniversary. She used a temporary Rietveld installation in Arnhem of 1955 later used for the sculpture garden of the Kröller-Müller Museum. Cassina had designed a MutAzioni series for the occasion and the Black and Green Rietveld was one of that series.
