One of the highlights of this year’s Outsider Art Fair in New York (until 22 March) is a series of paintings by the self-taught folk artist Sam Doyle. The 20 works on The Gallery of Everything stand come from the collection of the publisher Bob Roth, a co-founder of the Intuit Art Museum in Chicago, which is dedicated to outsider and self-taught art. Prices range from $35,000 to $85,000. Doyle was a self-taught artist from Saint Helena Island, South Carolina, born into a Gullah family in the US Lowcountry, a remote region of islands, marshes and rivers where descendants of enslaved Africans preserved rich linguistic and cultural traditions.
