Scarce double page map of Portugal in original color, from Rizzi-Zannoni, the Royal Geographer of France.
One of the most highly detailed large format maps of Portugal published in a commercial atlas during the period. Includes exceptional detail, showing towns, roads, rivers, mountains, lakes, and many other minor details. The engraving style is uniquely topographical for the period.
Decorative cartouche in original color. Second title at the top in French. A fine wide margined example.
