Over on the right is my more recent stocking of the lower levels of the Mentzer DM's book sample dungeon. Here are some scans of my original version (a few rooms restocked judging by the eraser marks).
I redrew the second level map for some reason, and in pen!
The stocking of the dungeon on the back of the map.
The third level, keyed on the map, featuring Bargle's lair and a teleporting portal to the dragon.
A random dungeon, not sure what this is part of, on the back of the third level.
[edit--of course, Blogger put in all my pictures backwards. Fixed now.]
