Sent to me by a friend – this ghost sign is virtually invisible from street level but can be viewed from various windows facing Stevenson between 2nd and New Montgomery. The Electric Railway and Manufacturers Supply Co was an early 20th century electrical supply company located at 24 2nd Street. Oh look, you can buy a copy of their catalogue here.
I love finding secret signs like this. It makes me feel like I’m somehow “winning” against the ever-changing cityscape and it’s shifting vantage points.
