"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."
American outsider artist, Henry Darger created a war-inspired fantasy around pre-pubescent girls with boy parts while toiling as a janitor and never receiving recognition until his artist landlord unearthed his treasure trove shortly before his death.
Henry Darger wrote thousands of pages about the Child Slave Rebellion, a sci-fi or fantasy story chronicling the Vivian Girls as they tried to escape from hostile rulers. He also illustrated the novels through a collage process utilizing newspaper and magazine cut-outs.
