Now this sort of thing could be very sell-able! Inkjet print onto 11x14 art stock. On consignment at tourist shops? You'd probably need to make them a little less 'computery' though.
I saw tourists in Sausilito paying up to $350 for prints of hand drawn maps of the bay area.
In fact LOTR style maps of most tourist destinations would probably sell in tourist shops. England and New Zealand especially.
