Found a fascinating historical pic of the San Francisco waterfront circa 1913. This is about where Embarcadero Center stands today. Why is that 200 foot long Owl Cigar sign reversed?#ghostsigns #sanfrancisco

Early twentieth century photos show an Owl Cigars sign in reverse on a huge San Francisco wall. But why was it painted like that?

@ghostsigns Nice job!

@ihazrabies It doesn't really get much closer to a resolution, but it's now there for people to find, with what we know so far.

PS. If you follow the links to the Flickr images, there are some brilliant photos with other signs in them from the same shoot.
