"Throughout Jean Dubuffet's life, he collected "Outsider Art" i.e., Art by mentally deranged people, vagabonds, street urchins, and prisoners. He found inspiration in the seemingly asymmetric scrawling and the scratching of this kind of unintentional Graffiti and sought to convey that madness in his own Oil and Impasto Works. Most of his works appear as primitive and doodling that is almost too basic...[like] a kindergarten kid."
Alfred Wallis was a Cornish fisherman and artist. He painted his seascapes from memory, in large part because the world of sail he knew was being replaced by steamships. Having little money, Wallis improvised with materials, mostly painting on cardboard ripped from packing boxes, he also tore the cardboard to shapes that enhanced the shape of the paintings.
