The self-portrait series is Casas most exciting works date, and combines her early talents in fashion design and primary studies in studio photography. In this series, Casas idea was to set up a contrast between recurring themes found in Kahlo’s paintings, such as the prima donna character vs. the nun as holy relic martyr and victim, notions of femme and masculine dual sexuality, and the use of bright, vivid colors and symetric patterns. All typical of Kahlo’s visual leimotif which were influenced by her life’s struggles and observations of indigenous cultures and European realism, symbolism and surrealism.
