This a later barn, probably from 1920 or so as it has narrow horizontal siding a frame structure visible through its open door indicative of the later barns. These barns do not age as well as the earlier ones as the siding is thinner and more prone to failure exposing the critical frame members to the elements.
The painting is 11x15 inches on 300lb Fabrino Rough paper. This painting is sold. I am including a couple of shots here during the painting here on the blog. Enjoy! If you like to purchase painting on Etsy you can click here Up the Hill
