Everyone, from Pop artist Andy Warhol to American football great “Mean Joe” Greene, has been mesmerized by its memorable, hourglass figure.

We’re talking about the Coca-Cola Company’s legendary glass contour bottle, which debuted in 1916. The iconic vessel was the brainchild of designers at the Root Glass Company in Terre Haute, Ind., who were tasked with creating a beverage container that could be easily identified by shape alone. Their inspiration for the now legendary 6.5-ounce Coke bottle: the gourd-shaped cocoa pod.

These are just some of the historical tidbits that CBS Sunday Morning shares in a segment on the classic contour design, which Coca-Cola historian Phil Mooney calls the company’s “Holy Grail.”
