The holiday month has just begun and everyone seems excited about Christmas. While many associate the festival with carols and cakes and family gatherings, for the majority, Christmas is synonymous with ‘Santa Claus’.

But did you know, that the image of Santa Claus that is so famous today wasn’t always this way? Interestingly, prior to 1931, Santa was depicted as everything from a tall gaunt man to a spooky-looking elf.

When Civil War cartoonist Thomas Nast drew Santa Claus for Harper’s Weekly in 1862, Santa was a small elf-like figure who supported the Union. Nast continued to draw Santa for 30 years, changing the color of his coat from tan to the red he’s known for today.

Coca-Cola has had a huge contribution in forming the image of the holiday character. The company explains in detail some of the very interesting facts associated with Santa Claus.

1.  Santa Has Been Featured in Coke Ads Since the 1920s

The Coca-Cola Company began its Christmas advertising in the 1920s with shopping-related ads in magazines like The Saturday Evening Post. The first Santa ads used a strict-looking Claus, in the vein of Thomas Nast.

2. Coca-Cola Helped Shape the Image of Santa

In 1931 the company began placing Coca-Cola ads in popular magazines. Archie Lee, the D’Arcy Advertising Agency executive working with The Coca-Cola Company, wanted the campaign to show a wholesome Santa who was both realistic and symbolic. So Coca-Cola commissioned Michigan-born illustrator Haddon Sundblom to develop advertising images using Santa Claus — showing Santa himself, not a man dressed as Santa.

3. The “New Santa” Was Based on a Salesman

In the beginning, Sundblom painted the image of Santa using a live model — his friend Lou Prentiss, a retired salesman. When Prentiss passed away, Sundblom used himself as a model, painting while looking into a mirror. Finally, he began relying on photographs to create the image of St. Nick.

4. Santa Claus Got a New Friend in 1942

In 1942, Coca-Cola introduced “Sprite Boy,” a character who appeared with Santa Claus in Coca-Cola advertising throughout the 1940s and 1950s. Sprite Boy, who was also created by Sundblom, got his name due to the fact that he was a sprite or an elf. (It wasn’t until the 1960s that Coca-Cola introduced the popular beverage Sprite.)

5. Santa Became Animated in 2001

In 2001, the artwork from Sundblom’s 1963 painting was the basis for an animated TV commercial starring the Coca-Cola Santa. The ad was created by Academy Award-winning animator Alexandre Petrov.
