The first map to depict the San Francisco Bay Area goes up for auction
An extremely old, rare and valuable map of California will go on sale next week. Auctioneers claim this is the oldest depiction ever made of the San Francisco Bay Area.
The map was drawn and signed almost exactly 252 years ago by a Spanish explorer named Miguel Costanso. The original manuscript map of the California coast is estimated between $600,000 and $800,000 by Bonhams, the auction house selling the relic in New York.
