A black and white newsprint map of eastern United States depicting the Moral situation of the states vis-a-vis the issue of slavery. The “boundary of slavery” seperates the morally pure Northern abolitionist states from the immoral Southern slave states. The shading of the Southern states emphasizes the severity of the threat of westward expansion of slavery, particularly to the newly acquired Texas Republic.
A quote attributed to La Fayette below the map reads: “It is a dark spot on the face of the nation; such a state of things cannot always exist.”
