95% or more of the patriotic covers that exist today were printed between 1861-65. It is believed that no fewer than 7,500 and perhaps as many as 10,000 designs exist. A wide variety of subjects were used to inspire patriotic sentiment and gain support for and against secession. Civil War patriotic covers include famous faces (military and political), scenes from the battlefield, designs related to the Army and its regiments, state-themed designed, and perhaps as many as 1,000 distinctive caricatures.
