Mid-20th Century Amish Pastoral Scene Oil on Canvas by Harvey Milligan

Americana Amish farm-life oil painting by Harvey Milligan, circa 1950s. Charming character scale and composition (figures are very small). Although naive / Primitive in aesthetic, clearly the work of a skilled painter to compose such a detailed and vibrant pastoral scene on such a small scale.
