In the center of the greeting card's cover, place a classic VW Campervan, styled in a whimsical, hand-drawn manner reminiscent of Quentin Blake's lively illustrations. The van is painted in a retro teal color, with chrome accents gleaming brightly. The tires are adorned with whitewall trim, adding a touch of vintage charm. The windows are slightly ajar, allowing a sense of movement and adventure to seep into the scene.

To the right of the campervan, illustrate a single-tier heart-shaped wedding cake. This cake should be intricately detailed, echoing the elegant linework of Aubrey Beardsley. The cake is frosted in a rich ivory with delicate lace-like patterns etched into its surface. Atop the cake, position a dainty spray of white roses crafted with precision and subtle shading, echoing the delicate floral detail often seen in Beatrix Potter’s works.

Above the campervan, suspend a banner fluttering in an imagined breeze. Render it in a style inspired by the elegance of Maxfield Parrish, with swirling ribbon-like ends. The banner bears the inscription "Mr & Mrs Howard" in a whimsical, yet legible font, colored in soft gold to evoke a sense of celebration and importance.

Scatter bouquets of white roses across the foreground, rendered in lush detail, capturing the intricate layering of petals akin to the style of Edward Gorey’s intricate illustrations, yet with a lighter, celebratory touch. The roses appear as though freshly picked, with dewdrops glistening on their leaves.

For the background, employ a dreamy, Rockwell-inspired sky—a soft gradient transitioning from pale blue at the horizon to a deeper azure at the top, dotted with fluffy, well-defined clouds. Perhaps, in the spirit of Maurice Sendak, include a hint of playful mischief—a small, stylized bird perched on the campervan’s roof, chirping joyfully.

The overall composition is bustling with the richness of texture and detail, inviting the viewer into a narrative brimming with whimsy and classic elegance.
