Advanced D&D Dungeon Masters Guide

This is a vintage 1979 advanced dungeons & dragons dungeon Master guide by TSR hobbies. This book was used on many campaigns by myself. If you have a gamer that's into old books this is the book for them! many DM still refer back to this old dungeon Masters guide in their own campaigns because this book is amazing! pages are all intact no rips or tears. The only writing in it was from me in 1989. And that would be the two characters I ran while playing D&D. If you have a gamer in your life this would be a great Christmas gift. It is right around the corner haha. rule for initiative!!!
