Enamel and metal Coca-Cola bottle pin with "Marque Déposée" text.

The Coca-Cola bottle, often referred to as the "contour bottle," was designed in 1915 by the Root Glass Company and has become an iconic symbol of American culture and global branding. Its unique shape was intended to be recognizable even in the dark or when broken. The "Marque Déposée" inscription indicates that this particular item was registered as a trademark in a French-speaking region, suggesting a European market focus for this promotional item.

This pin likely served as a promotional item or collectible, capitalizing on the widespread popularity of the Coca-Cola brand. Such pins were common in the latter half of the 20th century, especially during the 1980s, as companies utilized merchandise to enhance brand visibility and consumer engagement. The enamel and metal construction is typical for this type of collectible, designed for durability and visual appeal.
