It is the gelatin silver works of the surrealist period that remain the most sought after by admirers: "Portrait of Ubu" (1936), "29 rue d'Astorg", black and white, collages, photomontages or superimpositions. The photograph represents the central character in a popular series of plays by Alfred Jarry called "Ubu Roi". The work was first shown at the Exposition Surréaliste d’objets at the Galerie Charles Ratton in Paris and at the International Surrealist Exhibition in London in 1936. She also participated in Participates in Fantastic Art, Dada, Surrealism, at the MoMA in New York the same year.
