As of November 2002, I have only found 3 fully recovered pictures of The Back, as most pictures taken have had their cameras damaged. I have tried to recover them as best I can, but they are prone to suddenly corrupting.
This one above is the first image I found, besides the renovation logs. This is the first instance (that I have found, anyway) of The Back generating rooms that don't exactly follow Ol'Jears.
Above is an extremly low-quality image of "The front side" mentioned in the renovation logs. Although, there are some differences that tell me this is an early picture of The Back first trying to generate other kinds of rooms.
This one is interesting. I found it while searching for video footage, and found this on an image board. I have contected the user who posted it, but have yet to get a reply. Stay tuned for any updates regarding this area.
