There is also 2 copies of the TSR Dungeons and Dragons Basic Rulebook; one is in very good condition, the other is worn.
There are 2 books of Advanced Dungeons and Dragons Adventure Record Character Sheets from 1980 (green cover)
Lastly, there are two boxes.   One is Set 3: Companion Rules that contains two books: Players Companion (Book 1) and Dungeon Masters Companion (Book 2).   The other box is from the 1980 TSR Dungeons and Dragons Expert Set, which has no books (it is just the box).  Both boxes show shelf wear.  
This whole collection has been in storage for years but is still in good condition.  The pages are all readable and it's mostly the covers that show wear.  Wear varies, so if there's a module or book you're interested in, please message me. 

Everything is sold as is.
