I went back and read an online discussion we had about this schoolhouse a couple of years ago. It is called the Belmont School, and from a school book I found at the site, we dated it to the 1930s. I kept the book - I've added some some images below.
Also, take a look at this story about a 2018 attempt to preserve the school, along with some history. I might make another stab at this subject - I've been enjoying painting structures lately.
This is another little 5x7" acrylic on canvas.
