Were you aware that Google Earth has a "History" icon that opens a slider for historic aerial data? It's pretty fantastic.

One of my pasttimes is to compare different map sources/times for the same location.

I wrote a python2 tool that parses any URL like the one you gave, and outputs links to the geo location at many map providers:

Well now I have to explorer SF in 3D in 1938. This might take a while.
