The front cover of the birthday card bursts with vibrant, cartoonish energy, pulling from a medley of classic styles. Imagine a retro gaming console, reminiscent of an old arcade machine, as the main focal point. Its joystick is oversized and whimsical, like something out of a Bill Watterson drawing, with a vivid, candy-red color and a round yellow button flashing with excitement.

Perched playfully atop this console is a cheeky Jack Russell Terrier, drawn with exaggeratedly large, expressive eyes akin to Osamu Tezuka's iconic style. Its fur is a vibrant mix of brown and white patches, each outlined with a bold black line, adding a touch of Schulz’s Peanuts charm. The dog’s tongue flops happily out to one side as if it's ready to jump into the screen.

In the background, pixelated clouds, inspired by the landscapes of early video games, drift lazily across a sky of gradient blues, transitioning from bright azure to a gentle twilight indigo. Dotting this sky, like power-ups from a classic game, are floating digital hearts and stars, rendered in an 8-bit style that nods to Hergé’s clear line technique.

The Jack Russell’s tail wags exuberantly, with little cartoon motion lines, while its paw playfully rests on a stack of pastel-colored cupcakes. Each cupcake is topped with sprinkles, their hues echoing the vibrant palette of Winsor McCay's works. Among these cupcakes, a small one sports a bright orange candle, flickering with a fiery tip.

Arching above the entire scene is a pixelated rainbow banner, with the word "MAX" emblazoned in bold, blocky letters that feel like they've jumped right out of a Charles Schulz comic strip. The letters are multicolored, alternating between electric blue, bright pink, and sunny yellow, echoing the playful chaos of a retro game world.

The ground beneath this whimsical scene is a checkerboard pattern, alternating between shades of green and purple, lending a sense of movement and depth, a nod to the dynamic panels of Will Eisner's storytelling. It's a chaotic, colorful concoction that blends nostalgia with a playful canine twist, perfect for a birthday celebration card.
