I thought I'd upload a couple of great draft, wraparound, custom map images I started, but never finished (and never will). No time, plus my D3 license stopped working when I upgraded my OS.
The files are very high resolution, and huge, so I probably won't keep them uploaded forever. Snag them while you can.
There are two maps here - JPG, and original layered Adobe files so they will be easier to manipulate. I hope some ambitious mapmaker makes a nice working map with them, and other people will be able to enjoy the work I started!
