I’ve always enjoyed looking at the mural inside my city post office. It seems that, per Wikipedia, “from 1934 to 1943, the Procurement Division of the United States Department of the Treasury commissioned murals in post office buildings across the country. Part of the New Deal, the stated objective of commissioning United States post office murals was to secure artwork that met high artistic standards for public buildings, where it would be accessible to all people. The murals were intended to boost the morale of the American people suffering from the effects of the Depression by depicting uplifting subjects the people knew and loved.” ~SueBee

That mural should have cheered people up, I would think.
