The cover illustration is a comical blend of adventure, fashion, and music, set in a vibrant, cartoon world. At the center of the scene, we see an adventurous character resembling Indiana Jones but with a quirky twist—he's wearing a pair of crisp, selvedge jeans instead of the usual rugged pants. The jeans are rolled up to reveal the distinctive white and red edge of selvedge denim, giving him a hip, modern flair. He's swinging mid-air on a lasso, reaching for a golden record perched precariously on a ledge. The golden record is engraved with "The Killing Joke's Greatest Hits" in bold, eye-catching letters, its shine reflecting beams of light around the scene.

Below him, a bustling jungle unfolds, filled with oversized birthday cakes instead of the usual temple ruins. The cakes are intricately decorated with colorful icing, featuring layers with patterns of music notes and tiny denim patches, giving a playful nod to the themes. Amongst the cakes, small animals resembling a mix of Peanuts' Snoopy and Tintin's Snowy dash around, wearing miniature fedora hats and jeans. A few of these animals are seen holding musical instruments—a tiny saxophone, a trumpet, and a drum—ready to perform an impromptu birthday concert.

In the background, lush cartoonish foliage frames the scene, with oversized candles emerging like jungle trees, their flames flickering cheerfully. Hidden within the leaves are subtle nods to classic comics—perhaps a little "Calvin and Hobbes" style tiger peeking through, or a "Maus"-inspired mouse explorer watching the scene unfold with binoculars.

The sky is a bright cartoon blue, dotted with fluffy clouds shaped like musical notes, enhancing the whimsical, adventurous atmosphere. Above, a small biplane flies by trailing a banner that reads, "Wishing You a Denim-tastic Birthday Adventure!" in bold, fun letters. The scene is rich with vibrant colors and playful details, making it a feast for the eyes, inviting viewers into this quirky birthday escapade.
