Cahun produced an astonishing number of self-portraits in various guises such as aviator, dandy, doll, body builder, vamp and vampire, angel, and Japanese puppet. Some of Cahun's portraits feature the artist looking directly at the viewer, head shaved, often revealing only head and shoulders (eliminating body from the view), and a blurring of gender indicators and behaviors which serve to undermine the patriarchal gaze. Scholar Miranda Welby-Everard has written about the importance of theatre, performance, and costume that underlies Cahun's work, suggesting how this may have informed the artist's varying gender presentations. Cahun's published writings include "Heroines," (1925) a series of monologues based upon female fairy tale characters intertwined with witty comparisons to the contemporary image of women; Aveux non avenus, (Carrefour, 1930) a book of essays and recorded dreams illustrated with photomontages; and several essays in magazines and journals. In 1932, Cahun joined the Association des Écrivains et Artistes Révolutionnaires, where she met André Breton and René Crevel. Following this, Cahun began associating with the surrealist group and later participated in a number of surrealist exhibitions, including the London International Surrealist Exhibition (New Burlington Gallery) and Exposition surréaliste d'Objets (Charles Ratton Gallery, Paris), both in 1936. Cahun's photograph from the London exhibition of Sheila Legge standing in the middle of Trafalgar Square, her head obscured by a flower arrangement and pigeons perching on her outstretched arms, appeared in numerous newspapers and was later reproduced in a number of books. In 1934, Cahun published a short polemic essay, Les Paris sont Ouverts, and in 1935 took part in the founding of the left-wing anti-fascist alliance Contre Attaque, alongside André Breton and Georges Bataille. Breton called Cahun "one of the most curious spirits of our time." In 1994, the Institute of Contemporary Arts in London held an exhibition of Cahun's photographic self-portraits from 1927–47, alongside the work of two young contemporary British artists, Virginia Nimarkoh and Tacita Dean, entitled Mise en Scene. In the surrealist self-portraits, Cahun represented herself as an androgyne, nymph, model, and soldier. In 2007, David Bowie created a multi-media exhibition of Cahun's work in the gardens of the General Theological Seminary in New York. It was part of a venue called the Highline Festival, which also included offerings by Air, Laurie Anderson, and Mike Garson. Bowie said of Cahun: You could call her transgressive or you could call her a cross-dressing Man Ray with surrealist tendencies. I
