How well does Blackmoor MMRPG line up with Living Greyhawk?

[aldarron]

Does this Outdoor Survival Board hail from that time when a number of people were all using parts of the same map?

I believe it actually does. Not sure how Mr. Arneson used it since (presumably) he had the environs outside Castle Blackmoor mapped out early on. Like I said, I would think it could be used for the area 'beyond the borders of the map'. I'm not actually even sure how Mr. Gygax used it, though I suppose The City of Greyhawk was represented as the one city along the river (with Castle Greyhawk being in the same hex).

The OS map was called "province One" and was simply tacked on to the bottom of the Blackmoor map.
