This impressive mid-nineteenth-century map, titled 'Johnson's Hindostan or British India,' was published by A. J. Johnson and Benjamin P. Ward during the 1860s. The map provides a comprehensive geographical view of the Indian subcontinent during the height of British imperial administration, stretching from Afghanistan and Tibet in the north down through the Deccan Peninsula, Ceylon, Birmah (Myanmar), Siam (Thailand), and the Malayan Peninsula. Vivid hand-coloring highlights administrative boundaries, princely states, and regions under direct British control. Adding significant historical and architectural value, the sheet features three detailed inset maps of key colonial metropolitan centers—Bombay, Madras, and Calcutta—as well as a prominent steel-engraved architectural vignette of the Government House in Calcutta in the upper left corner. A key near the top center indicates rail roads, capitals of empires, presidencies, and principal towns, documenting the rapid infrastructure expansion across the subcontinent. Framed by Johnson's characteristic interlocking Gothic strapwork border, this map exemplifies the high aesthetic and informational standards of American commercial atlas publishing in the Victorian era. It stands as a vital historic document reflecting 19th-century geopolitical cartography and British colonial geography in South and Southeast Asia.
