The majority of art in my house is outsider art. Self taught work makes me believe in art, whereas most contemporary work makes me question that belief. You can get affordable, wonderful work from Creativity Explored in San Francisco. They will ship from their online store, but the best is to go there in person. You can flip through thousands of works in the flat files and you can meet the artists. They also have ceramics. Some iconic outsider artists that I love - for all of you God posters, look into B.F. Perkins. Mose Tolliver paintings on wood are true genius. Marcia Weber Art Objects is a good source - also a great place to visit in person. My husband and I did a road trip to her gallery in Alabama and started in New Orleans - take the back roads not the main highways, it’s longer but it's worth it. Speaking of New Orleans, it's a great place to look for Hatian vodou flags - sequined, hauntingly beautiful and mysterious.
