This year marks the 100 year anniversary of the most famous packaging design of all time: the Coca-Cola bottle. In honor of the event, Robert Klara over at AdWeek has an excellent article on the history of the Coke bottle. According to the article, the iconic design was selected from attempts from ten glass companies to meet Coke’s demand for “…a bottle which a person will recognize as a Cola-Cola bottle even when he feels it in the dark. The Coca-Cola bottle should be so shaped that, even if broken, a person could tell at a glance what it was.” Earl R. Dean of the Root (hey, how about that!) Glass Company designed the bottle, which has evolved over the years. The article includes several great infographics, including this one which discusses the features of the bottle that make it so unique.

So, Happy 100th Birthday Coca-Cola bottle! You don’t look a day over 50.
