I don't know if this is the right place, but I have a character that believe himself to be expert mapper of Elanthia. He is not so hot, but has created a set of in-character maps and logos. Right now, I have less than a dozen maps located at www.theseoldgames.com ( http://www.theseoldgames.com/p/maps-for.html ).
Plainly, they do not correspond to any map currently available to players and they have obvious flaws, however, I would hope that they qualify as outsider art. If you own a fan site, you can use these maps and logos for artwork. I must warn users that these maps are very flawed and often contain either outright mistakes or possible details which are misleading. They are more flavor than description. Each has a touch of madness or OCD to them.
Since I have a tiny body of work, please feel free to suggest areas or updates. Having assistance in the form ideas for areas would help me create more images. Additionally, if someone has a thematic need, I can modify these documents for you.
Either request here or leave a comment on the site.
Thank you in advance and happy adventuring,
Player of Damianio and Magarven the Mad.
