This late eighteenth-century copperplate engraved map depicts the Iberian Peninsula, comprising Spain and Portugal, as published for Mathew Carey's landmark American edition of William Guthrie's 'Geography Improved' (c. 1795). Printed in Philadelphia, Carey's publication represented a monumental achievement in early American map publishing, providing the new republic with detailed cartographic works of European regions compiled from leading contemporary sources. The map provides detailed geographic coverage of Spain, Portugal, the Balearic Islands (Majorca, Minorca, and Ibiza), and the northern coast of Africa including Tangier, Ceuta, and Melilla. The traditional provinces and kingdoms are clearly delineated, including Galicia, Asturias, Biscay, Navarre, Aragon, Catalonia, Old Castile, New Castile, Valencia, Murcia, Andalusia, Granada, and the historical regions of Portugal. Topographical hatching illustrates mountain chains like the Pyrenees, accompanied by extensive labelling of rivers, capes, bays, and prominent towns. An understated oval cartouche in the lower right corner encloses the title 'SPAIN and PORTUGAL, from the best AUTHORITIES.' Scales for British Statute Miles and Spanish Miles are positioned in the upper right corner, while the top margin retains the publication line indicating its origin in Carey's American geography atlas.
