Some people have a coffee order. Others have a Diet Coke. This calendar is for the second group: the box shows Santa raising a Diet Coke bottle beside a red delivery truck rolling through a snowy village, with silver accents and a big 2026 on a crisp white and red background.

A Can With a Cult Following

Diet Coke launched in the United States in 1982 and quickly became one of the best-selling soft drinks in the world. Its silver can became a style statement, the “Diet Coke Break” adverts of the 1990s turned an afternoon pause into a pop culture moment, and today devoted fans swear the fountain version tastes best. For many people it is less a drink than a small daily ritual.

The red truck on the box ties it to the Coca-Cola holiday tradition: the illuminated trucks of the “Holidays Are Coming” adverts have marked the start of the season for millions of families since 1995.

What Waits Behind the Windows

The 24 designs mix Diet Coke cans and bottles with festive characters, Santa, a snowman, a polar bear, the delivery truck, a little camper and a handbag or two. Each piece is flat acrylic printed on both sides. The numbered photo shows the whole set together; it does not tell you what sits behind each window.
