Front of card:
Featuring an illustration of a person's bare buttocks, humorously depicted with a brightly coloured party blower inserted between the cheeks. The party blower is exploding with confetti-like decorations. To the left of the image, bold white text on a blue background, playing on the word "cracking" as a pun related to both the explosion of the party blower and the person's behind. The style is cartoonish and lighthearted.

Text reads:
"Have a cracking birthday."

Back of card:
Scribbler logo.
