The cover of the greeting card is set in a whimsical garden teeming with vibrant colors and quirky characters. In the center of the scene, a couple stands surrounded by a lively day party in full swing. The couple, both wearing comically oversized "40" birthday crowns, are dressed in retro 80s attire — think leg warmers and neon windbreakers. They're holding hands, but each hand holds a different item. The man clutches a slingshot-shaped balloon, reminiscent of Calvin and Hobbes’ playful spirit, with a cheeky grin on his face that echoes Charles Schulz's iconic Peanuts expressions. The woman holds a cupcake with a single sparkler, its glittering sparks captured mid-fizzle, a nod to Walt Disney’s magical touch.

Around them, a zany array of partygoers includes a robot with a birthday sash that reads "Happy Over the Hill!", tipping its top hat like Osamu Tezuka’s Astro Boy might. In the background, a giant cartoon cat, with a bemused expression like a character from Gary Larson’s The Far Side, lounges in a hammock strung between two whimsical, Dr. Seuss-style trees. A small penguin waiter, in a tuxedo, serves drinks on a tray, a humorous nod to Art Spiegelman’s knack for adding unexpected elements to his scenes.

A banner stretches across the top of the garden, made of vintage comic strip panels like something Will Eisner might have used, spelling out "Life Begins at 40!" Each letter is being held up by a parade of tiny, energetic squirrels dressed in explorer gear, a playful homage to Hergé’s adventurous Tintin. In the foreground, a small table is set up with a vinyl record player spinning a disc, its needle bouncing cartoonishly in sync with the beats, and surrounding it, a dance floor filled with animated animal characters inspired by Winsor McCay’s dreamlike creations. Each animal strikes a dynamic dance pose, perfectly capturing the energy and movement in Bill Watterson's Calvin and Hobbes. The whole scene is a vibrant tapestry of whimsical chaos and fun, a visual celebration of turning 40.
