The Gulf of Palermo.
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 harbor around Palermo from Cape de Gallo to Mt. Gerbino.
Condition is very good. Image size 5.25 x 6.5 (inches).
