Bywaters mural sure looks more like Texas than Strong's in Decatur.
Decatur painting hung in 1939 at old post office, now a visitors center, is a block away from the Wise county courthouse. The Farmersville post office is in a smaller town, still in operation and bigger.
The entire downtown in Farmersville and includes the post office as an Historic Place. Many tourists visit on the weekend. Talking to a postman about how it was preserved like the old days and how the post office served the farmers shipping produce and live chickens. He agreed and told me that the week before they had a couple of crates filled with live baby chicks, and complained how they made a lot of noise.
