This building at the corner of Foothill and Daisy is for sale. I'd guess it was built in the early- to mid-20th century, despite the 19th century look. The fact that the builders took the trouble to make a mundane thing such as a vent into an attractive detail may speak about the rest of the building. It may not. I didn't notice the missing flashing until I blew up the photo. That just makes me like it more.
