The image to the left which shows Alameda, California is from a close-up of an old map that was made of the San Francisco Bay Area in 1854. Notice “Auster Bank” (Oyster Bank) near San Leandro Bay and Bay Farm. Click images for much bigger pictures.
The picture to the right is from the same map, but shows a larger area. Of note: “New York Pacific”, “Pt. S. Quentin”, “Mission San Jose.”
The image to the left is the full map that the close-ups above came from.
