Scarce Spanish Maritime Chart of the southern coast of Brazil and the Río de la Plata, published by the Hydrographic Department of Spain. Essential auxiliaries for sailors, these charts fulfilled a noble mission that went beyond Spanish-flagged vessels. In the Argentine Confederation, its most relevant authority was at that time the governor of Buenos Aires, Juan Manuel de Rosas.

The graph includes large boxes of Montevideo, “Buenos Ayres” and Puerto Maldonado, and extends along the Argentine coast just south of San Clemente del Tuyú, at the southern end of the Samborombón Bay.
