Dungeon Master's Guide

The 1979 Advanced Dungeons & Dragons Dungeon Masters Guide, first printing The last of the three core AD&D 1e rulebooks and the densest, packed with Gygax's tables, magic items and advice, under Sutherland's City of Brass cover. Together with the Monster Manual and Player's Handbook it completes the trio most first edition collections are built around. The first printing has unusually clear tells: the letter D in the angled yellow AD&D banner is cut off, the book runs to only 232 pages, the flyleaf is yellow and there is no printing information inside. A copy that checks all four boxes is the one to look for.
