The front cover of the birthday greetings card features an imaginative, whimsical scene that seamlessly integrates all the requested themes into a delightful tableau. The scene is set on an outdoor stage that has been magically transported into a sunny park. This stage, much like the famous clock tower from "Back to the Future," features a large clock with its hands set at 10:04, hinting at the time-travel theme.

On the stage, a group of lively bunnies are putting on a grand musical theatre performance. Each bunny is dressed in vintage 1950s clothing reminiscent of "Grease," with poodle skirts, leather jackets, and pompadour hairstyles. They are in the midst of an energetic song-and-dance number, and you can almost hear the music from their cheerful expressions and dynamic poses.

At the center of the stage stands a colossal, whimsically-decorated birthday cake with the number "22" on top in sparkling, edible glitter. The cake is multi-tiered with layers that feature scenes from "Back to the Future" and musical theatre, such as Marty McFly on his skateboard and bunnies performing Broadway hits. The cake is so grand that it seems to be a part of the set, with bunnies dancing around it and even a couple of them playfully popping out of the cake itself.

To the left of the stage, there is a DeLorean time machine, complete with its gull-wing doors open and vibrant, neon lights. A couple of bunnies dressed as Doc Brown and Marty McFly are leaning out of the car, waving and grinning.

The background shows an audience of more bunnies sitting on picnic blankets, clapping and cheering. Among them, some bunnies are holding "Happy 22nd Birthday" signs, and others have tiny musical instruments, as if they were part of an impromptu orchestra. Balloons in various shapes float around, adding to the festive atmosphere.

Above the stage, a banner stretches across, reading "Happy 22nd Birthday!" in a font reminiscent of the "Back to the Future" title logo, adding the final touch to this enchanting and celebratory scene.
