Greyhawk (Supplement I), softback supplement for Original D&D, 2nd printing
Dungeons & Dragons – Additional Rules for Fantastic Medieval Wargames Campaigns Playable with Paper and Pencil and Miniature Figures – Supplement 1: GREYHAWK
The first (and most important) supplement for Original Dungeons & Dragons. This was the supplement that introduced such D&D staples as thieves, the spells magic missile and charm person, beholders, umber hulks, carrion crawlers, gelatinous cubes and the deck of many things among many others.
Very rare. This copy is a second printing from 1975 with the original GK logo (for Gygax and Kaye), and is in very good condition.
