Interesting street view on Google maps.
Plug in 176 Second Avenue North, Nashville Tennessee to Maps. The big brick building is clearly marked AT&T, but the occupant to its right (facing the building) has the second story blurred out, straight on, where from either side, it just shows the same blank brick.
Hmm.
