There are only a few things I like doing better than strolling down Chelsea’s galleries on a freezing weekend. My first stop was Demisch Danant, one of my most favorite design galleries, which shows an exhibition,“Michel Boyer: The Rothschild Bank, Paris 1970,” dedicated to the furnishings Boyer, a celebrated decorator during the 70s designed for the Rothschild Bank on rue Lafitte in Paris. The landmark commission resulted in some extraordinary pieces that represent the zeitgeist, the aesthetic vocabulary of 1970s France. I loved the addition of “Prayer Rug” by Sheila Hicks, the American textile artist who has lived in Paris since 1964, and who was commissioned by Boyer for Elie de Rothschild’s private collection. This is what I call an extraordinary exhibition that contributes to the study and scholarship of 20th-century design.
