Here's a delightful discovery--one of the oldest images we've found of Sheridan and Montrose, from 1913. You can see a street car off to the left. I honestly can't say what perspective this is; the scene looks nothing like this today. My first guess is that Sheridan is the one with the streetcar, and we're looking east down Montrose. Thoughts?
