From now canonical and widely celebrated artists including Nek Chand, Alo?se Corbaz, Henry Darger, Madge Gill and Adolf W?lfli, to contemporary practitioners such as Noviadi Angkasapura, Marilena Pelosi and Shinichi Sawada, these individuals passionately and obsessively pursue the pictorial expression of their vision.
