It was actually this map that gave me the idea for the suggestion. http://forums.gleemax.com/showthread.php?t=1042981
(From the spoiler block in the second post)

I don't need anything fully detailed, or with colour. If it could be dated, as the example, that would be preferable, but not neccessary. Otherwise, I am simply looking for a more professional appearance to the map I created, one that would be at home in a fantasy setting of old.
