The number does the work. A huge coral seven is drawn as a road across the front, complete with a dashed white centre line, and seven patterned racing cars are strung along it: a green pickup and a small numbered racer at the top, then a blue number four, a white number three, a blue jeep and a red racer running down the diagonal.

Bunting stretches across the top of the yellow card, navy and blue stars sit in the corners, and confetti and paper curls fill the space between. The line above the track reads When it comes to being a great 7 year old.

Inside, it finishes in pink lettering: You are leading the pack, then Hope Your Birthday is a Winner, over three more little cars. The panel around it is clear for a message.

A folded card of approximately 5 by 7 inches with a matching envelope, for a seventh birthday specifically rather than a general one.
