In the foreground of the card, create an animated and detailed hand-drawn illustration reminiscent of a Norman Rockwell style yet infused with a dash of Edward Gorey's whimsical eeriness. Central to the scene, design a quirky, mushroom cloud-shaped birthday cake, its tiers adorned with miniature vault doors and safety signs, subtly hinting at Vault 45. The cake is decorated with an abundance of candy fallout shelter signs and topped with a figurine resembling Fallout Boy, cheekily waving a sparkler in one hand.

To the left, depict a slightly exaggerated Nuke rocket, leaning nonchalantly against the side of the cake. The rocket is adorned with a myriad of vibrant stickers depicting tiny Vault 45 logos and tiny cartoonish radiation symbols in neon yellows and greens, reminiscent of Aubrey Beardsley’s intricate linework but playful in color.

In the background, channel the fantastical essence of Maurice Sendak by illustrating a dream-like sky, a mix of pastel blues and purples with wispy clouds forming suggestive shapes of balloons and confetti, celebrating the birthday theme. Among the clouds, in a playful twist, the name "Oliver" is subtly formed within a stream of festive, floating banner clouds.

To the right, include a tiny, whimsical landscape dotted with vault-like houses inspired by Beatrix Potter, with each abode displaying little flags featuring the Vault 45 emblem. Add small, charmingly odd creatures peering curiously at the birthday scene, a nod to Arthur Rackham's storytelling details.

This greeting card front cover should present a captivating and humorous visual narrative, engaging viewers with its colorful, detailed elements while celebrating Oliver's birthday in a world inspired by Vault 45, Fallout Boy, and the fantastical imagination of classic illustrators.

Generated with these themes: Fallout boy, Nuke , and Vault 45.
