The building to the right of the car in
e_r's picture appears to be part of the California Market Center (aka California Mart) at 9th and S Los Angeles. The first two buildings were completed in 1963 and 1965, so the one in the picture could be either. I'm still trying to identify the building on the left - the California Market Center doesn't appear in the background of the impact pictures, so maybe the main image is some sort of composite.
