From the Belle Époque to the Roaring Twenties, Paris continued, more than ever before, to attract artists from all around the world. This cosmopolitan city was both a capital where innovation thrived and a place of tremendous cultural influence. It brings together almost four hundred works by Robert Delaunay, Sonia Delaunay, Marcel Duchamp, Marie Laurencin, Fernand Léger, Tamara de Lempicka, Amedeo Modigliani, Chana Orloff, Pablo Picasso, Marie Vassilieff, and many others. It also features clothing designs by Paul Poiret and Jeanne Lanvin, jewellery by Cartier, a plane from Le Bourget Musée de l'Air et de l'Espace, and even a car on loan from the Musée national de l'Automobile in Mulhouse. Through fashion, cinema, photography, painting, sculpture, and drawing, as well as dance, design, architecture, and industry, this exhibition showcases the rich creativity of the period 1905-1925.

The exhibition, organized both chronologically and thematically, draws its originality from the geographical perimeter on which it mainly focuses, i.e., the Champs Élysées. This district was a veritable cradle and hub of Modernity. At the time, the Grand Palais hosted the latest in artistic creation at the Salon d'Automne and Salon des Indépendants every year, where the public could discover works by Douanier Rousseau, Henri Matisse, and Kees van Dongen amongst others.
