Embellished with large compass in the bay and a rococo-style title cartouche that incorporates a distance scale.

2) This chart details the mouth of the Rio de la Plata with Buenos Aires shown on a grid plan. The bay is marked with soundings, anchorages, and shoals. Decorative rococo-style title cartouche with distance scale.
