The boy spies of Philadelphia : the story of how the young spies helped the Continental Army at Valley Forge
A juvenile adventure novel by James Otis, published in New York by A.L. Burt Company in 1897, about boys acting as spies for the Continental Army at Valley Forge. The four cover illustrations are dark, woodcut-like scenes with bold lettering, showing a rider on horseback, a soldier with a musket in woods, a scout beside a campfire, and sailors with a figure in period dress. A designer might take the strong black-and-white contrast, the boxed title typography, and the rough hand-cut line work for historical or adventure-themed covers.
