These shots are from two places with great 1930s murals in SF: Coit Tower (inside, on the ground floor), and the Rincon Center former postal facility. The coit tower murals were highly controversial at the time they were painted, which was right as the tower opened (it was a tribute to the firefighters of SF by a wealthy patron). Since the artists received government funding, and the theme of some of the murals was borderline (if not blatantly) socialist, there was an outcry and a couple of the more provocative murals were painted over. Today the ones that survived capture the spririt of the 1930s, and the people who worked in the farms and factories, beautifully).
