A 4x5 transparency shows the ornate deco entrance to Sutro Baths. Two square columns rise on either side supporting the marquee reading Tropic Beach Sutro Baths. The photo was taken from a distance and from above; beyond the baths, the Pacific Ocean and Marin County coastline recede to the north under cloudy skies. A balloon vendor stands outside the entrance on the sidewalk. Handwritten on the envelope: Sutro Baths, SF. Beach
