This rare sheet with two charts of Puerto Rico was published by Lopez de Vargas Machuca (1730-1802), Geographer to the King of Spain and one of the most distinguished Spanish cartographers of the eighteenth century. The top chart depicts the waters surrounding San Juan with soundings and navigational hazards. A bird's-eye plan of the city is depicted, with surrounding fortifications and a numbered key identifying 27 locations. Lopez based his map off of the manuscript map by Francisco Ramon Mendez, Primer Piloto of the Royal Spanish Armada. Mendez surveyed the area in December 1782 aboard one of the most famous Spanish War ships of the period, the San Juan Nepomuceno.

The bottom chart depicts the western coastline of the island from Rincon to Cabo del Aguila, known as the Aguada Nueva. This chart was based on the work of Thomas Jefferys from his 1762 Plan of the Aguada Nueva de Puerto Rico.
