Photograph of an exterior of the Los Angeles and San Diego Counties exhibit at the World Fair in San Francisco, 1930. A tall concrete building is visible at center with windows extending up the entire length of it. No windows are visible on the portion of the building to the right, but flags are visible flying from the roof. Three signs are visible on the building reading, "Los Angeles and San Diego Counties", while other signs reading, "San Diego" and "Los Angeles" alternate above four entryways. Multiple men, women, and a few children can be seen walking in front of the building. Trees and a second building are visible in the left background.
