This comprehensive mid-19th-century steel-engraved map depicts the entire continent of Asia, published by Alvin Jewett Johnson in New York. The map provides a detailed geopolitical overview of regional powers during the era, including the expanse of the Russian Empire across Siberia, the Qing Dynasty Chinese Empire, British India, Arabia, Persia, and the Japanese archipelago. Distinct color washes distinguish political territories and imperial spheres of influence across the continent. Framed within Johnson's signature decorative fretwork border with ornate corner stars, the map offers rich topographic and hydrographic details, outlining major river systems, mountain chains such as the Himalayas, and desert regions like the Gobi. Ocean trade routes, island groups in the East Indies, and historic Silk Road hubs throughout Turkestan are carefully rendered, serving as an exceptional snapshot of American cartography in the 1860s.
