The Fortean Times have just put a fantastic article online about Outsider Art.
Although the term ‘Outsider Art’ is used to describe artists from a number of different backgrounds, the art of people who have been declared insane or mentally ill is especially prominent.
The work can often be intricate, intense, disturbing and delightful, sometimes all at the same time, and is largely produced by people with no formal training or contact with the mainstream art world.
The above image is part of Adolf W√∂lfli’s picture ‘Irren-Anstalt Band-Hain’.
