Secession Exploded

I have nothing to say about this illustration, except that the drawing style strikes me as extremely unusual for period. Here's the description:

This strongly anti-Confederate satire is a fantastical vision of the Union defeat of the secessionist movement. A hideous monster representing secession emerges from the water at left. He is hit by a charge from a mammoth cannon "Death to Traitors!" operated by Uncle Sam (right). A two-faced figure representing Baltimore, whose allegiance to the Union was at least questionable during the war, pulls at Uncle Sam's coattails. The explosion sends several small demons, representing the secessionist states, hurling through the air. Prominent among them is South Carolina, in a coffin at upper right. Tennessee and Kentucky, two Southern states internally divided over the secession question, are represented by two-headed creatures. Virginia, though part of the Confederacy, is also shown divided--probably an acknowledgment of the Appalachian and eastern regions' alignment with the Union. Among the demons is a small figure of Tennessee senator and 1860 presidential candidate John Bell, with a bell-shaped body. In the foreground is a large American flag on which Winfield Scott, commander of the Union forces, and a bald eagle rest. Despite the imprinted copyright date, the print, according to the inscription on the Library's impression, seems to have been registered for copyright on June 14 but not deposited until July 10, 1861.

The illustration is attributed to William Wiswell of Cincinnati.
