Colorful map of northern China, Central Asia, Mongolia, Siberia, Korea, and Japan, published by Henry Teesdale in London.
The map shows the territory of the Chinese Empire extending much farther north than it does today.
Teesdale was a London-based map publisher. He was an early Fellow of the Royal Geographical Society, elected in 1830. Teesdale partnered with John Hordan and William Colling Hodson, but this arrangement dissolved in 1832. Afterward, he continued to work on his own and periodically with colleagues like John Crane Dower, Christopher Greenwood, Josiah Henshall and others. He published a variety of atlases and separately-issued maps. His business was quite successful, as he registered as a partner in the Royal Bank of Scotland in 1845.
