This map is from an uncommon set of small travelers maps by Luffman that could serve as a quick reference for even the more remote parts of the world. Many were coastal and port depictions that detailed cities locations, good points to anchor, as well as large landmarks. Here a view of the area around Port Louis in Department of Morbihan in France.
