Rare reduced version of Muller's rare map of 1754, which is more commonly known by the 1758 re-issue, both of which were published in St. Petersburg.
Describing the 1754 issue, Streeter notes that "This . . . map confirmed the existence of a body of water between Asia and America, the subject of much dispute during the previous two hundred years. It also showed the Kurile Islands correctly and suggested the outline of Alaska and the Aleutian chain. Though the Russian discoveries had been shown on the Delisle map . . .published in 1752, . . . this is the first map to give an approximate picture of what is now the Alaska peninsula. . . ."
The present map is copied from the 1758 issue, with the word Russes in the title changed to Russiens and the 1758 date given in the title cartouche. A rare edition of this seminal map.
