Patriotic covers were a popular form of visual propaganda and became a collector’s item during the Civil War. Produced both in the North and South, these envelopes featured patriotic imagery and slogans, although some—primarily printed in the North—employed stereotypical and exaggerated images of the speech, dress, and physical characteristics of African Americans.

This patriotic cover was issued during the Civil War and depicts the bonds of slavery being unlocked by the point of a Union bayonet.
