Charles Winstanley Thwaites spent the first half-ish of his life in the midwest, where he worked as an artist, printmaker, and educator. You can see some examples of his work at the website for the Smithsonian American Art Museum.
Thwaites created four post office murals. I’m almost ashamed to say that one, Lumbering, is in my hometown of Greenville, Michigan, and I never knew about it. A couple of months ago, I shared my surprise that I grew up about 6 miles from a post office mural. Today, I learn that my dad worked in post office that has a mural. SO much art taken for granted. Thwaites other murals are: Threshing Barley (Chilton, Wisconsin), One Hundredth Anniversary (Columbus, Wisconsin), and Charles W. Thwaites (Plymouth, Wisconsin).
