This illustration depicts an underwater scene centered on a large, dilapidated shipwreck resting on a sandy seabed. The vessel is rendered in dark, weathered browns with shattered windows and decaying wooden beams, suggesting long abandonment. A diver in a vintage, spherical metal helmet and a brown suit stands on the left, looking toward the wreckage while bubbles rise toward the surface. The scene is framed by a light blue water backdrop, with thick, swaying strands of green seaweed dominating the right side of the frame.
Various marine creatures inhabit the environment, adding vibrant pops of color. A pale, translucent jellyfish with long, delicate tentacles floats near the upper left. Smaller, bright blue fish swim in schools around the shipwreck, while two larger, reddish-pink fish with wide mouths and spiky fins swim prominently in the foreground near the seabed. Near the diver, a cluster of rounded, mauve-colored coral or anemones sits on the sandy floor, complemented by dark, submerged debris and patches of green aquatic plant life.
The artwork follows the distinct ligne claire comic style, characterized by clean, bold black outlines and flat, expressive colors. The lighting is bright and even, lacking deep shadows, which gives the underwater landscape a clear and accessible, storybook quality. The composition is balanced, with the verticality of the seaweed on the right contrasting with the massive, diagonal bulk of the shipwreck, creating a sense of depth and mystery beneath the waves.
