  1. You can tell if a street scene was pre or post elevators by counting the number of stories in the buildings. If the maximum height is five stories, it's pre elevator, since five stories was considered to be the most a building could have and still rent offices on the upper floor. Buildings higher than five stories almost always contained some kind of elevator.
