Good point.
For those of you who are not familiar with the reference, prior to this excellent (REALLY) map by Mike Schley, I would say that there have been two maps of Greyhawk (specifically, the Flanaess, that's the part of Oerth that we think of when we say "Greyhawk") that have really stood out.
The first, of course, is the Darlene Map. One of the most iconic fantasy maps ever, and the OG (Original Greyhawk!) map.
The second are the maps of Anna B. Meyer, who has been making amazing maps of Greyhawk for some time (and heladry to, if that's your bag).
Visit her website and see for yourself-
Obviously, with the renewed focus from WoTC on Greyhawk, I certainly hope that they will be leaving space for the Anne Meyers of the world, who have kept Greyhawk alive during the long winter of WoTC's inattention.
