Anson’s post office represents the late 1930s rationalist reduction of the classical orders: flat panels of brick replace pilasters; the cornice is a tall, flat band of stone flush with the brick panels below; and deep-set windows and doors are voids between the brick panels. Inside is Jenne Magafan’s mural Cowboy Dance (1941) sponsored by the Section of Fine Arts of the U.S. Treasury Department. The mural depicts the annual Texas Cowboy’s Christmas Ball and caused a local uproar when the presence of a little brown jug was spotted. First painted over, it is now back in view. Anson has always been “dry” and remains so. The annual ball is still held in the WPA-funded facility (2300 Avenue G), a large bowstring-trussed barn clad in random stonework. Across the street from it is a matching bathhouse for the public swimming pool.
