A lithograph by Joseph Pennell from his 'War Work in America' series, depicting early biplanes in flight.

Joseph Pennell, a prolific American illustrator and printmaker, produced this lithograph as part of his 'War Work in America' series. The work captures the early development of aviation during the First World War. Pennell focuses on the mechanical form of the aircraft, which he depicts as small, bird-like silhouettes against a vast, atmospheric sky. The title, 'The Larks', draws a direct comparison between the natural flight of birds and the emerging technology of military aeroplanes.

The composition utilises a vertical orientation to emphasise the height and scale of the sky. Pennell employs rapid, gestural marks to render the clouds, creating a sense of movement and turbulence that contrasts with the rigid, geometric shapes of the biplanes. The ground below is rendered with heavy, dark horizontal lines, providing a stable base that anchors the ethereal scene above. This print reflects the artist's interest in documenting the industrial and technological shifts occurring in the United States during the conflict.

Pennell was well-known for his ability to find aesthetic interest in industrial subjects, from construction sites to manufacturing plants. In this piece, he avoids the glorification of combat, choosing instead to focus on the technical and visual reality of flight. The lithographic process allows for a soft, charcoal-like texture, which gives the clouds a hazy, expansive quality. The work serves as a historical record of the era, documenting the transition of the sky into a space of human activity and machine-driven exploration. It remains a clear example of Pennell's technical proficiency in printmaking and his observational approach to the modern world.
