Album cover artwork featuring a chaotic collage of illustrated figures, a bomber plane, and text bubbles.

The artwork features a chaotic, densely packed black-and-white ink illustration with selective splashes of colour. At the top center, the words "GREEN DAY" appear in large, bold, mustard-yellow bubble lettering, set against a backdrop of billowy white clouds. A fighter jet flies diagonally across the scene, trailing smoke that curls toward an explosion represented by a yellow starburst shape at the bottom center. A small blimp floats near the top left, bearing the text "BAD YEAR," while numerous tiny, frantic human figures and surreal creatures populate the landscape below.

The style is reminiscent of a detailed comic book or underground zine drawing. The composition is frantic and energetic, drawing the eye across a wide array of vignettes, including a person holding a tray of food, a figure in a top hat, a monkey-like creature in the foreground, and various suburban architectural elements. The word "dookie" is printed in red bubble letters at the bottom, mirroring the font used in the upper text. The overall aesthetic is gritty, punk-inspired, and visually dense, relying on high-contrast linework to define the overwhelming activity and anarchic energy of the scene.
