Welcome to CornerSpotter, Curbed's regular game in which you, fair readers, consult archival streetscape photos or postcard illustrations to identify the building(s) and/or location presented. Time to tap that reservoir of urban minutiae and flaunt it before your fellow readers. Fire away in the comments, and we'll reveal the correct identity and backstory tomorrow.
This 1920s photo shows the early construction phase of a longtime gathering spot for excitable Chicagoans. At completion, the structure briefly became the largest of its type in the world and the first to boast air conditioning. The story of its removal and replacement is common to many cities, but that didn't make it any less painful to legions of sentimental admirers. Small commemorative tokens of the building are littered around town, but all the masses get is a parking lot with a plaque. What's the building and what corner did it once rule?
