“In [Sonia Delaunay’s] studio,” a 1927 advertising flyer promised, “you will know that you are seeing something new, something that… will transform your life into a work of art.” Delaunay’s Paris atelier in the twenties was producing textiles, carpets, garments, movie sets, furniture, books, and paintings—everything a person might need for an artful existence and all made in the “simultaneous” (simultané) style that the artist developed with her husband, the painter Robert Delaunay.
