I knew there was something up with this building, which is now the headquarters of the Service Employees International Union. It clearly had been a much older structure with a Modernist update in the central portal.

Sitting on Clifton Avenue, which apparently used to be Old Manchester Road, this was Clifton Heights Elementary School, and there was even a small police station directly across the street when this was a small streetcar suburb far from the central city.

You can see the original building peeking out on both the left and right.
