This is a black and white illustration with a dramatic, high-contrast style. The composition is dominated by a large, solid black circle, representing the moon, which takes up most of the upper portion of the image. Below the moon, a detailed cityscape is rendered in fine, delicate lines. The city features a cluster of buildings with pointed spires, suggesting a medieval or gothic style. There are also trees and a landscape with rolling hills or a wall surrounding the city. The contrast between the stark black moon and the detailed white cityscape creates a strong visual impact. The artist's signature, 'William T. Morton', is visible in the bottom right corner.
