Here's 4th St. in Santa Ana, from the intersection of Main, looking northwest...
...just after the 1933 earthquake, and again (from the same angle) more recently..
The building in the center, which lost its entire facade, was the Woolworths. Later, the store moved to a location that's barely visible on the left side of the image. The building on the right, with the fancy griffin motif under the window, is the Otis Building. It's had some major changes to it over the years, which is obvious when you look at early photos of Downtown Santa Ana.

Don't forget that the Dana Point Historical Society's annual home tour is this weekend.
