The central artwork features an antique-style, hand-drawn map of the world set against a deep blue, framed background. A large, ornate banner stretches across the center bearing the words "Maclean's $100,000 TREASURE HUNT" in bold, classic typography. Below the banner, the continents are depicted in warm, golden-tan tones, with delicate grid lines and compass roses overlaying the oceans, styled to resemble a classic nautical chart.
Surrounding the continents are various whimsical and legendary maritime elements. In the lower left, a muscular Poseidon-like figure with a trident rises from the sea near South America. Toward the bottom center, two mermaids swim gracefully in the Indian Ocean, while near the coast of Asia, a large green sea serpent coils through the water. Sailing ships of different eras, ranging from classic galleons to modern cruise liners in the top corners, are interspersed across the globe, alongside small depictions of whales and treasure chests.
The illustration uses a soft, painterly aesthetic with earthy tones for the landmasses contrasting against the dark, monochromatic blue border. The composition is structured and balanced, evoking a sense of old-world adventure and discovery. The overall style is reminiscent of vintage storybook maps or historical exploration charts, using fine ink-like linework to define the geographical boundaries and mythical creatures.
