Today, I scanned it.
It took about 3 hours and half my sanity.
But it is done.
(Click the link above to get the map in various resolutions, and I've also added a black & white version!)
Four long sheets of wrapping paper.
I scanned it bit-by-bit, in 16 bits. Then stitched it together in GIMP, corrected everything that wasn't lining up.
This is a thing of beauty.
It will probably never see play... But hey, perhaps I (or you, dear reader) can use parts of it?
