“There are several ways to define outsider art, the Museum of Halle Saint Pierre gives way to people who don’t have any relationship with the art world. They do art because they like making it. Their work is a purely spontaneous experience art. Outsider art could therefore be thought of as art created outside of the centre of the art world made by people living and working on the periphery” Roger Ballen 2020
