Art brut today

40 years ago, the Collection brut was christened by Jean Dubuffet in Lausanne. As early as the '45s, in the aftermath of the Second World War, in a particular context where establishment, academism and artistic pedagogy were tiring creative impulses, art brut had the advantage of offering creation without "culture", wild, without rules or code. Since then, Art Brut has evolved, it has been accepted in major contemporary art exhibitions, and the art market has understood its value and the lucrative business that can be made from it... In short, what is the state of art brut today?
