In 1964, the year in which she had a solo exhibition at the Louvre, Delaunay also held her second solo show at the Galerie Bing, for which she designed a striking poster and this signed invitation card employing bold colour and equally bold graphic forms. Throughout her career, she used colour as an expressive language bringing about new ‘poetic’ combinations in abstract paintings and textile designs.
