I posted this 1953 picture of the Civic Center yesterday.
USC Digital Library
Then I found these 1955 pictures looking northwest from somewhere near the Hall of Justice/North Broadway. The roughly horizontal road across the middle of both shots is North Hill Street. I did think about stitching the two pictures together, but the photographer moved between shots. I've done my best to darken the top of both pictures as the originals were almost white, and there was very little contrast in the background.

On the right, the Hollywood Freeway is now complete and in use.

Just for fun, I tried to recreate the USC shot using Google Earth. It doesn't take many fingers to count the number of buildings that are still standing 60 years later!
