Meanwhile, in San Francisco...

Thanks to my interests, I follow a bunch of history and map blogs. That blog list often turns up articles like this gem, tracking down the source of a nicely-tiled entrance to a now-missing building at 7th and Hubbard in San Francisco.

You can't say enough nice things about people who combine pictures on the modern-day ground, Sanborn maps, and a good bit of gumshoe research to pull out a story.
