The birthday card illustration presents a whimsical Mario Kart race in full swing, set on a track that spirals around a giant birthday cake shaped like a mushroom. The cake has vibrant red frosting with white polka dots, mimicking the iconic Super Mushroom from the Mario universe. At the forefront, Yoshi is in the lead, joyously steering his kart, which is humorously decorated with balloons shaped like dinosaur eggs. The racetrack is cleverly made of rainbow sprinkles that twirl around the cake, creating a visually delightful circuit. Behind Yoshi, Mario is giving chase in his classic red kart, his face determined yet playfully exaggerated, reminiscent of Gary Larson’s expressive characters.

Along the sides of the track, a crowd of Toads cheer enthusiastically, each holding little flags that spell out "Happy Birthday Joseph!" in bright, bold letters. Above them, floating blocks are tied with blue helium balloons that have cartoonish smiling faces, channeling a mix of Schulz's and Disney's charm. To the right of the scene, there’s a surprise twist: Bowser and Princess Peach are racing side by side, but instead of rivalry, they’re laughing and trading jokes, as if in a playful truce for Joseph's special day.

In the background, a bright blue sky dotted with fluffy, comic-strip-style clouds frames the scene, and one cloud spells "Joseph" in a curly, bubbly script, as if written by Hergé himself. A small Lakitu floats above, holding a birthday flag instead of the usual race-start traffic light. The entire scene is a lively, colorful homage to the birthday boy, blending the zany excitement of a Mario Kart race with the warm, nostalgic touch of beloved comic artists, creating a uniquely charming and personal birthday greeting for Joseph.
