The front cover of the birthday greeting card depicts a bustling yet whimsical transport hub, reminiscent of a lively cityscape. In the foreground, there is a vibrant, multi-tiered birthday cake shaped like a grand central station, complete with a clock tower at the top showing the birthday person's age as the time. The cake-station is bustling with miniature trains and trams, their windows glowing warmly, adorned with streamers and balloons.

To the left of the cake-station, a meticulously detailed traffic roundabout is buzzing with tiny cars shaped like various birthday items - a cupcake car, a present-shaped vehicle, and a candle-powered scooter. Each vehicle has tiny, cheerful passengers waving as they zoom around the roundabout.

In the background, an intricately designed bridge arches across the scene, its railings festooned with bunting and colorful flags spelling out "Happy Birthday." The bridge connects to a quirky, cartoonish skyscraper resembling a stack of gift boxes, each window lit up and showing different festive scenes, such as people dancing, a cake being cut, and presents being unwrapped.

Above, the sky is dotted with whimsical hot air balloons shaped like balloons themselves, in various bright colors, with passengers throwing confetti down onto the bustling scene below. A banner towed by an airplane reads, “All aboard the Birthday Express!”

The scene is rich in detail, with elements like street signs replaced by party hats, lampposts resembling lit candles, and a central fountain spraying colorful, confetti-like water. The overall composition is a playful blend of transport infrastructure and birthday celebration, creating a unique and festive visual story.
