Detailed engraved map of the world issued by Henry Teesdale in London in 1834.
The United States reaches the West Coast just in the north, having not acquired the Mexican Territory in California in the Southwest.
The Canadian Arctic is still poorly delineated, and there is barely a hint of the Antarctic in the south.
The interior of Africa and New Guinea are still largely unmapped.
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.
