The first of these porcelain signs were roughly eight-by-eight feet and got right to the point: “Ice Cold Coca-Cola Sold Here,” they proclaimed. The Coke bottle depicted on the sign was straight sided—the company’s trademark curved bottle, which resembled the contours of a hobble skirt and was nicknamed “Mae West,” was not widely used until 1920.

Some tin signs were embossed, giving the brand’s famous logo relief, while others were made of aluminum and coated in celluloid, which was less durable than porcelain but worked fine in interiors such as soda fountains and bars.

An especially popular sign from 1914 featured a model named “Betty.” This marked a shift for the company away from high-brow celebrity toward something approaching sex appeal, although the young lady’s attire and flirtatious gaze is certainly tame by 21st-century standards. Other signs on cardboard from this period admonished customers to ask for Coca-Cola by its full name, which was an effort by the company to combat competitors trying to capitalize on the parts or even misspellings of the brand’s good name.

World War I brought severe sugar shortages, so very few signs were produced during these years, but in the 1920s the Coke advertising machine was in full swing again. One classic sign from this decade is the gas-station sign, which often had a chalk circle or triangle built into the sign so station attendants could write in that day’s gas price. Larger signs had what are known as “privilege panels” above the Coca-Cola panel itself. These gave retailers space for signage of their own, in close proximity to the Coca-Cola panel, of course.

The 1920s were also when flange signs first came to prominence. These signs featured stenciled-and-fired enamel artwork on both sides of the sign, with a small right-angle flange at one end so the sign could be attached to a building and read by customers walking in opposite directions.

Another famous vintage Coca-Cola sign shape is the so-called red button, which was made by porcelain sign manufacturer Temco of Nashville, Tennessee, among others. The red button sign shape found its way onto Coca-Cola clocks, metal trays, and calendars, as well as flange signs. Shield signs forced the logo into a triangular shape, while rectangular signs were jazzed up by placing the logo within a fishtail shape.

As with the rest of popular culture, Coca-Cola signs changed with the times. For example, the frames of Coca-Cola signs exhibit distinctively Art Deco touches through the 1930s, while the signs themselves often feature mirrored or reverse-painted black glass. In fact, despite the Depression, the 1930s were a big decade for Coca-Cola signage—in 1934 alone, for example, the company offered 28 different styles of signs to its retailers, plus four versions designed just for coolers.

The 1940s saw the arrival of a new Betty on Coca-Cola signs, but new metal signs were put on hold due to the needs of World War II. Untold numbers of porcelain signs were scrapped for the war effort, which, of course, has led to their current scarcity and popularity among collectors. After the war, porcelain signage fell out of favor for less-expensive alternatives such as aluminum and eventually plastic.
