The real reason why this particular iconic representation of America’s national bird never caught on, is in the tailfeathers – shaped to follow a border no longer in existence by 1848. The western borders of the subsequent independent and later US state of Texas are recognisable, for now as the dividing line between the US and Mexico. The feathers follow the US inland border as it moves north, and disappears out of sight at the area disputed with Great Britain.
Meanwhile, the great inland empire of Louisiana is already being divided up into US states, with Louisiana and Missouri separated from the ‘mainland’ of the formerly French lands.
This map was published in Philadelphia in 1833 by Carey & Hart, in a now extremely rare atlas, the Rudiments of National Knowledge, Presented To The Youth of the United States, And To Enquiring Foreigners, By A Citizen Of Pennsylvania.
