In the center, there's a cartoonish, animated F1 car wearing a party hat, zooming ahead while leaving a trail of colorful confetti. The borders of the card are adorned with various cartoonish racing elements such as checkered flags, tires and comical mechanic characters of Hispanic and Caucasian descent, displaying the festive theme. The decoration also includes balloon-shaped race flags scattered around. At the top of the card, 'Happy Birthday' is written in bold letters, styled like a race team logo, perfectly blending the themes of speed and celebration.
