It's my photo of a historic photo of Oak Hall, the mansion of F.M. "Borax" Smith on the Arbor Villa estate. We viewed where it stood on the recent Oakland Urban Paths walk, but there's not much there to see except where things were. You can read more about Arbor Villa, "Borax" Smith, Mary Smith and more on the Oakland Wiki. You can contribute to Oakland Wiki, too, and write about Oakland's past and present.
