At the end of the evening celebrating Kertész's opening at Au Sacre du Printemps and Seuphor and Dermée's publication of Documents internationaux de l'esprit nouveau, Kertész gathered the group together for a photograph. In the center, stands Ida Thal, who shared the exhibition with Kertész. To the right are Adolf Loos, Piet Mondrian (in hat) and Michel Seuphor (sans chapeau).
