The Looking Glass Hatch diagram

Here is the diagram of The Looking Glass Hatch. These are some very big promotional stills for "Greatest Hits." You can really see a lot the detail on the diagram if you click for a larger image. These photos are from the ABC promotional stills. [Added third picture - You can see a crudely drawn person standing in the round area to the left of submarine docking area. It appears that this is where Bonnie and Greta came from.]
