The Spanish Ship "San Carlos" sails into San Francisco

On August 5, 1775, the Spanish ship San Carlos, commanded by Juan Manuel de Ayala, entered what would soon be called San Francisco Bay. Unnoticed by such early naval explorers as Sir Francis Drake and Sebastián Vizcaíno, the bay had been sighted by land during a Spanish scouting expedition six years earlier.

Here is a link for the drawing, which can be zoomed in on. Great fun seeing what the City was like before the Gold Rush.
