|The Main Entrance
As far as I know, the main entrance to the office suite is seen only in the first season. Here are some samples.
1 Episode 1. The door has curious sidelights and
is on a flat wall.
Picture 2 Episode 25. Out side of teh
door is a hallway.
Picture 3 Episode 31. Still the odd
sidelights but now the door is on a wall segment that
prottrudes into the room.
