Nicolas Ledoux is a French artist, member of the collective Ultralab. His work is exhibited in France and abroad. He began with the drawing that has made his reputation but he also uses paint or markers printer. All the work of Nicolas Ledoux plays on lure: artist / critic. He wants to set a new critical art practice and thus refuses the system decoys. At an exhibition gallery, the commercial reason means small formats because accessible to the public, he decided to do the opposite by making exaggerated large formats. He remains critical in the face of the art history and the criticism of art history and invites the public to do the same about his work.
