Oakland Piedmont California original oil painting is painted with a palette knife and a brush and is 100% handmade. The city of Piedmont in the East Bay of California is a bit of a geographical oddity. It’s around 2 square miles in size and is surrounded on all sides by the city of Oakland. It's an old "town in town", quiet and beautiful residential area with multiple greenery. All sides are painted. The signature is available on the front and back of the painting.
