In this playful and whimsical scene, a cartoon world comes alive on the front cover of the birthday card. At the center is a lively soccer field, painted in lush greens reminiscent of the iconic Celtic Football Club grounds. The pitch is bustling with animated characters: a jubilant Celtic FC player, donned in the traditional green and white hoops, is about to kick a football. The football, however, is comically oversized and unmistakably shaped like a giant birthday cake, adorned with green and white icing, and a single, crooked candle perched at the top.

On the sidelines, an older female character stands out—a delightful caricature of "Mum." She has short, curly hair, wears a Celtic scarf wrapped proudly around her neck, and sports a big, joyful smile. She's holding a vibrant green and white flag, waving it excitedly, as her not-so-svelte figure conveys warmth and charm.

In the sky above the field, fluffy white clouds form the words "Happy Birthday Mum!" as if painted with the tip of a brush, with a tiny animated figure—a mischievous leprechaun—hanging onto the last exclamation mark with glee. The stadium seats in the background are packed with colorful, cheering fans, and a cheeky seagull flies across the scene carrying a little Celtic FC banner in its beak.

To the side of the pitch, a cartoon scoreboard cheekily reads: "Mum: Forever Young, Age: None of Your Business," adding a humorous touch to the birthday scene. The entire illustration is filled with vivid colors and whimsical details, capturing the joyful energy of a birthday celebrated by a Celtic FC enthusiast.
