Folk Art by definition, is the art produced by self-taught people - in other words, those who have not studied at art school. However today, the term "Folk Art" is also used to describe craft techniques that have been passed down from generation to generation. Then, there's Outsider Art, which is art that is created outside of the norm. That is to say, without guidelines or accepted standards. There's also Visionary Art. It seems that there are those among us that have a spiritual force guiding them to create works of art, usually with a strong spiritual message - this is called visionary art.
