Whether you've encountered some spectacular New England family portraits in a shop in New Hampshire or an intriguing example of "prison art" in the Midwest, a collection of quilts in a New York gallery or a piece of beyond-kitsch bottle cap art you found at a gas station in Mississippi, you've been experiencing American folk art. That’s a term that takes in a vast of amount of territory, territory relating to time (when it was created), media (what's it made out of) and quality.
