Existing comment: 5ยข Franklin on Free Soil Party circular, September 1848

The Free Soil Party was a third party in the presidential election of 1848, when Martin Van Buren was their candidate. Their sole platform was preventing the spread of slavery into the new territories acquired during the Mexican-American War. The first U.S. postage stamp, issued in 1847, was used to send their political circular through the mail.
