I've got a very big post coming up on another building with a rich history. I did most of the preliminary research a couple months ago, and I'm finally getting around to preparing the post.
As a teaser, here's a photo from the early 1950's. The building we want is the one in the background. It's still around (the building in the foreground isn't). Can you guess which building it is? (The answer is revealed in the comments)
