**Scene Description:**

Imagine a whimsical birthday celebration set in a vibrant, action-packed universe. The scene is bursting with color and detail, seamlessly combining Marvel superhero elements with the classic style of Adidas.

**Background:**

The backdrop of the card features a lively cityscape inspired by classic comic book styles, reminiscent of Quentin Blake's energetic line work. Skyscrapers rise with intricate details, their windows reflecting bursts of confetti and streamers cascading from above, in bright, eye-catching colors like reds, blues, and yellows.

**Foreground:**

Dominating the foreground is a larger-than-life, hand-drawn Hulk in Adidas Superstar sneakers. He's wearing an Adidas track jacket, its iconic stripes rendered with precision. The Hulk is in a mid-stride, striking a dynamic pose as if he's charging through the party, echoing the energetic compositions of Norman Rockwell's work.

Beside the Hulk, Spider-Man, in his iconic suit, is swinging from a web that elegantly arcs across the card's upper section. His web intertwines with colorful balloons that feature the Adidas logo and birthday motifs. The balloons shimmer in metallic hues of gold and silver, inspired by Maxfield Parrish's radiant palette.

**Birthday Table:**

To the left, there's a birthday table set up like a dynamic spread from Maurice Sendak's world, covered with a comic-book style tablecloth decorated with Adidas logos. The table is filled with intricately detailed, hand-drawn cakes shaped like Captain America’s shield, Iron Man’s helmet, and Thor’s hammer. Each cake is colored vividly, using deep reds, blues, and silvers, with highlights adding a three-dimensional feel.

**Characters:**

Scattered around the scene, a diverse group of partygoers dressed as various Marvel superheroes sport Adidas gear, their expressions and postures captured in the detailed style reminiscent of Arthur Rackham. Wolverine is seen attempting to cut a slice of cake with his claws, while Black Panther hands out party favors, all wearing Adidas apparel customized with superhero motifs.

**Other Elements:**

In the bottom right corner, Rocket Raccoon and Groot are seen setting off party poppers, which explode into more Adidas-branded confetti, swirling in a dynamic gust across the card, reminiscent of Gustave Doré's intricate detail.

The card's border is subtly styled with vines and tendrils in the vein of Aubrey Beardsley, wrapping around the edges and incorporating both the Marvel and Adidas symbols cleverly into its design.

This illustration blends the fantastical elements of a superhero universe with the energetic vibe of a birthday celebration, all wrapped up in the lively aesthetic of hand-drawn art.
