Incumbent President Martin Van Buren drives "Uncle Sam's Cab," a carriage pulled by a blindered horse, which wrecks on a pile of "Clay." The carriage founders in the path of a locomotive, really an assemblage of a "Hard Cider" barrel, a log cabin, and the head of Whig presidential candidate William Henry Harrison on wheels.
Like "The Political Dancing Jack" (no. 1840-27), another crude but boldly designed woodcut, "The People's Line" was probably published by Huestis and Company and Robert Elton. Its imprint lists the two addresses used by these publishers on other prints during the 1840 campaign.
