Establishing Borders: The Expansion of the United States, 1846-48 |
|
This globe demonstrates the newness of the border line after 1848. Plates to print the paper of this globe were struck in 1846, showing Mexico as extending up to Oregon Territory. However, the globe was actually produced at a later date. Instead of changing plates (an expensive process), the company simply changed the color overlay to indicate new U.S. territory. |
