This is a primitive, vintage miniture painting / pin. This work of art would display well with a miniture collection on a what-not shelf! Painted on wood with a safety pin carved in the back. Country farm sceen, cottage or barn? Certainly vintage but perhaps antique. I would guess it's oil or acrylic, but I don't really know. Remarkable details! 1 3/4" square approx. Minor spots are visible in the sky, please zoom in to view.
