A unique art gallery devoted to so-called “outsider art” opens this week in Scotland. The gallery’s founder, a former art therapist, says that she intends to showcase what she calls Art Extraordinary: “‘visionary imagery inspired directly from the unconscious’. Many of those who produce it suffer from mental illness, but by no means all. Some are simply recluses, making art in private with no intention of showing it to anyone else.” The gallery will be the first of its kind in the UK.
