In 1912, the National Biscuit Company (today Nabisco) created a cookie that would go on to become one of the top-selling cookies of all-time: the Oreo. Despite its long history, there’s probably a lot you don’t know about the Oreo, so Buzzfeed offers up nine facts about the iconic cookie.

One of the more interesting facts is the design stamped into every Oreo cookie. The current version was settled upon in 1952, and features the word “OREO” in a circle topped with a two-bar cross. The design also contains exactly 12 flowers, 12 dots and 12 dashes. Why you ask?

According to The Atlantic, the circle and cross around the word “OREO” is a variation on the Nabisco logo, which is either “an early European symbol for quality” or a Cross of Lorraine, an emblem used by the Knights Templar during the Crusades. The dots and flowers might be a rendering of four-leaf clovers or a cross pattée, another symbol favored by the Knights Templar.
