A patriotic allegory illustrating the cover of sheet music for a song composed by William Vincent Wallace with words by George P. Morris. The theme of the indissoluble union of North and South is evoked here, no doubt in the context of debate over the Compromise of 1850. The artist expresses the concept by two female figures, crowned with diadems, standing together on a globe and holding the staff of a large American flag. The arm of the North (left) encircles the neck of the maiden representing the South. Before them is a large eagle, his talons gripping thunderbolts and his breast emblazoned with the word "Union." The eagle's wings spread to enframe the lower half of the oval picture. The upper half is ringed with stars. Into the distance stretch two great rivers, past large cities, toward rising mountains.
