The above map is a copy of the 1971 Great Kingdom Map given to Dave Megarry (designer of Dungeon!) by Dave Arneson at some point in the mid-70s. Megarry recently uncovered it in his files.
A different copy of the same map was shown in a video by Jon Peterson (Playing at the World) a few years ago.
The post linked below has my compiled notes comparing this map to the published WoG Folio setting, and the setting details mentioned in the novel Quag Keep:
Megarry's Copy of the Great Kingdom MapIf you are wondering where the City of Greyhawk is on his map, it isn't shown because presumably it hadn't been created when this map was drawn, or because the map doesn't indicate most cities. It would most likely be located near the south corner of the Nyr Dyv, slightly up river.
