This attractive map shows the newly acquired Louisiane as a United States possession. The territory was acquired shortly before the publication of this map, which is also dated 1803. The western third of the continent is under Spanish control with almost no inland detail and only a few place names along the coast including New Albion and New Georgia. The supposed course of the Columbia River is shown flowing into British Columbia. A possible Northwest Passage is shown via the Mer Selon Arrowsmith. The map extends to include the Caribbean islands and northern South America. Decorated by a simple block-style title cartouche and six distance scales.
Original outline color on watermarked paper with wide margins. There are a few faint spots of foxing, a bit of toning along the centerfold, and a printer's crease at right.
