A 4x5 transparency shows the intersection of Bay and Mason Streets in San Francisco. On one corner, a two-level parking structure is filled with cars in front of a five-story building. A large square marquee-style sign shows the words Akron and Mayfair. Signs along the lower level of the garage read Daylin Drugs, Mayfair Liquor, and Hickory Farms. Across the street is Veneto's, a restaurant with red-and-white striped awnings and a neon marquee sign with the words Veneto (twice), Dinner, and Cocktails. Cars and pedestrians navigate the streets and sidewalk. Handwritten on the envelope: SF Shopping Center.
