THE NATIONAL ERA, Washington, D.C., June 8, 1848 

* Mexican War about to end
* Treaty of Guadalupe Hidalgo
* Mexico - United States - Texas

Page 2 has a report headed: "The Treaty Ratified By The Mexican Deputies" which includes: "The express package received here today announces that the treaty has been ratified by the Mexican Chamber of Deputies...No doubt existed that the vote would be approved in the other branch of Congress by a large majority." followed by another item noting: "The despatch from the South which announces to you the confirmation of the peace news adds the following...'Orders have been issued calling in all the outposts of the American army..." with a bit more.
Great to have this report in a newspaper from the nation's capital. Four pages, nice condition.
