This is for a 1978 Advanced Dungeons & Dragons [AD&D] 3 Module lot.  Includes #9019 Dungeon Module D1 [Descent Into the Depths of the Earth], #9020 Dungeon Module D2 [Shrine of The Kuo-Toa], and #9021 Dungeon Module D3 [Vault of the Drow] all by Gary Gygax.  All modules are in good used condition with wear along the edges / corners and stains on the front / back cover.  The sword on the module D1 was colored.  Looks like D3 is missing the first 6 pages.  Didn't notice any other writing in any of the books; however, it is possible I may have missed something. All books are shipped in a box by USPS Media Mail.
