Rare map of North America, showing a remarkable NW Coast of America, including the recently discovered (by the Russians) Sea of the West. The NW Coast and area near Canada and the Bering Strait is based upon a mix of conjecture and early exploration and combines NW Passage mythology and a host of supposed discoveries. The Interior of North America is also quite unusual. This map is quite rare on the market. Only our second example in the past 10 years.
