After lifting her name from a popular brand of French school notebooks and stationery, Claire Fontaine declared herself a readymade artist[2][3] and began to elaborate a version of neo-conceptual art that often looks like other people's work.
This aesthetic approach that she describes as "expropriation", a way of giving an existential use value to pre-existing objects and artworks, also addresses the general crisis of singularity, which she describes as the individual and collective impossibility to give a meaning to one's life under the current political circumstance and the systematic surveillance, repression and countless limitations of our freedom.
[5] In an Interview with Circa Art Magazine in 2008 she states: "I think forming gangs, mafias, collectives, networks, bands of people is a way to survive in the hostile capitalist system and then eventually a way to become a pressure group, in order to transform these particular conditions.
In February 2020 she was invited by Maria Grazia Chiuri to create the mise-en-scène for Dior's Autumn/Winter 2020 collection for Paris Fashion Week which took place in the Les Tuileries.
The artist used the catwalk to perform an operation of Institutional Critique investing the floor and the ceiling; she presented Newsfloor (Le Monde Pixelisé) (2020) and several large suspended LED signs stating for example: Patriarchy Kills Love, When women strike the world stops, Feminine beauty is a ready-made or Patriarchy = Climate emergency.
