The Art of the Map: An Illustrated History Map Elements and Embellishments by Dennis Reinhartz is not about heraldry, however this is still a fascinating and beautifully illustrated book and contains lots of maps featuring heraldry. Many maps were dedicated to prominent individuals and their arms were often featured on the map.

Something I found interesting about this particular map and collection of arms was the blank one at the bottom. No design on the shield and no crest on the helm.
Looks like the artist was hoping for yet one more sponsor/subscriber/customer…
...we could put some money together and make a US map?
Lower right quadrant of the map is Dj Roeder Marck.
So, this is Rohan?
