Folk art encompasses art produced from an indigenous culture or by peasants or other laboring tradespeople. In contrast to fine art, folk art is primarily utilitarian and decorative rather than purely aesthetic. Folk Art is characterized by a naive style, in which traditional rules of proportion and perspective are not employed. Closely related terms are Outsider art, Self-Taught Art and Naïve art. The most famous faces of Folk Art are Eugene Von Bruenchenhein, Jon Serl, Sallie Hathaway. As a phenomenon that can chronicle a move towards civilization yet rapidly diminish with modernity, industrialization, or outside influence, the nature of folk art is specific to its particular culture. The varied geographical and temporal prevalence and diversity of folk art make it difficult to describe as a whole, though some patterns have been demonstrated.
