S. John Ross is great. I remember when he first demonstrated that woodcut technique on RPG.net. I'm still waiting for the right project to try that on.
S. John Ross is an extremely talented fantasy cartographer, plus a well-known, well-respected game author (especially for us GURPS players).
Here's a link to just a few of his wonderful maps: http://temphis.deviantart.com/gallery/
Here's a great link to a tutorial about those maps (which I also posted in the "tutorials" section): http://www.io.com/~sjohn/uresia-maps.htm
And here's a link to his very cool fonts: http://www222.pair.com/sjohn/fonts.htm
John has also given us a sneak peak of a map from his forthcoming Uresia project, as well as the permission to post it here. The PDF is attached below.
