Cartoon illustration of a diver finding treasure near a shipwreck with Tintin and Snowy in a shark-shaped submarine.

This vibrant comic-style illustration depicts an underwater scene filled with adventure. On the left, a diver in a classic vintage brass helmet and orange suit kneels on the sandy seabed, opening an ancient, treasure-filled chest. Above them, a sleek, shark-shaped submarine navigates through the water, carrying two characters—a man with a beard and a young man with iconic red hair—alongside a small white terrier.

To the right, the decaying skeletal remains of an old wooden shipwreck rest on the ocean floor, draped in seaweed and surrounded by small blue fish. A large, pale yellow jellyfish drifts near the center, while a shark swims curiously behind the shipwreck’s hull. The sandy floor is dotted with coral, sea stars, and two distinct reddish, spiny fish swimming near the treasure chest.

The artwork utilizes a clear, graphic line-art style typical of traditional comic books, featuring bold outlines and flat, bright colours. The ocean is rendered in a clean, solid blue, while the seabed is a warm, sandy tan. In the bottom right corner, a circular inset displays the faces of the young man and his terrier, accompanied by a blue rectangular banner containing the text "RED RACKHAM'S TREASURE."
