Striking sea chart of San Francisco Bay on thick heavy paper.
A rare separately issued engraved edition of this chart issued on heavy paper, with very wide margins and never folded.
The map shows the entrance to San Francisco Bay showing Ballenas Bay, Richardson's Bay, The City of San Francisco, Oakland, San Leandro and parts south, along with 3 large views of San Pablo, the entrance to the Bay from Yerba Buena, and a nice view of Alcatraz. Fabulously detailed images, with thousands of soundings, topographical land detail, street views, wharfs, rail lines, etc.
While the map appears on the market on the standard thin tissue paper, this thick paper engraved edition is quite rare.
