Rare early edition of Wyld's map of the United States, published in London at the conclusion of the Mexican-American War.

The was issued shortly after the Oregon Question had been resolved, but quite possibly prior to the signing of the Treaty of Guadalupe Hidalgo and shortly before the discovery of Gold in California

The map shows a massive Anglo-centric Oregon Territory, with the boundary at the 49th Parallel.

Upper California and Texas dominate the Southwest. In addition to contemporary borders, the map notes many important treaty boundaries and proposals, including

  • Adams-Onis Treaty Line (here called Treaty of Florida) which created the boundary between New Spain and Oregon Territory on February 22, 1819 and January 12, 1828
  • The proposed boundary between Mexico and the United States proposed by the Americans in 1835,
  • The US-Canada proposed border of October 20, 1818, etc.

The detail in the Northwest is especially impressive, with many Forts and other landmarks appearing which are not usually present on American maps of the same period. Texas is oddly misshapen along the Rio Grande.

James Wyld Biography

James Wyld Sr. (1790-1836) was a British cartographer and one of Europe’s leading mapmakers. He made many contributions to cartography, including the introduction of lithography into map printing in 1812.

William Faden, another celebrated cartographer, passed down his mapmaking business to Wyld in 1823. The quality and quantity of Faden’s maps, combined with Wyld’s considerable skill, brought Wyld great prestige.

Wyld was named geographer to Kings George IV and William IV, as well as HRH the Duke of York. In 1825, he was elected an Associate of the Institution of Civil Engineers. He was one of the founding members of the Royal Geographical Society in 1830. Also in 1830, his son, James Wyld Jr., took over his publishing house. Wyld Sr. died of overwork on October 14, 1836.

James Wyld Jr. (1812-87) was a renowned cartographer in his own right and he successfully carried on his father’s business. He gained the title of Geographer to the Queen and H.R.H. Prince Albert. Punch (1850) described him in humorous cartographic terms, “If Mr. Wyld’s brain should be ever discovered (we will be bound he has a Map of it inside his hat), we should like to have a peep at it, for we have a suspicion that the two hemispheres must be printed, varnished, and glazed, exactly like a pair of globes.”
