Because Rietveld circulated the menu during the evening, with the request to sign it, we know exactly who his table guests were.
On the menu, in addition to Rietveld and the chief architects’ signatures, you will recognize those of Le Corbusier, Hans Wegner, Marcel Breuer, Walter Gropius, Isami Noguchi, and Ernesto Nathan Rogers, among others. Remarkably, Karel Appel’s signature is also on the menu. He lived in Paris at the time and previously won the UNESCO prize.
