This is a bit of a mystery (to me anyway).
If I am reading it correctly, the sign below the dormer says Los Angeles House.

I found this in an older file of mine. It's possible it was located in Pasadena. (1890s?)
Maybe we've seen it before on NLA, but I don't think so.
p.s. I like the guy posing on the widow's walk. (atop the roof)
