It took 4 years to create OREO design. 

Symbols embossed on the outside surfaces of Oreo cookies link the merchandise to the alleged conspiratorial activities of the Knights Templar and Freemasons. The meaning of the Ornate design marked on every Oreo cookie is a riddle wrapped in an enigma between two chocolate wafers and a luscious cream filling. 

     A circle with a two-bar cross is a Nabisco logo and that stands for a European symbol of quality. The geometric pattern of a dot and four triangles radiating outward is a symbol that once again connects Oreos with the history of the First Crusade. The circle has many mystical meanings including a circle of life, creation, infinity, power, love, and most importantly, change. So, Oreo is not just a tasty round cookie, it's also a friendly reminder that the power of changing your life is all in your hands.

    The ornamental pattern of the wafer, however, is the Oreo’s visual signature. Stamped out by brass rollers passing over sheets of chocolate dough, the pattern consists of a series of four-leaf clovers around the word ”OREO,” which is set within the traditional trademark of Nabisco, its manufacturer  that trademark being a horizontal oval with what looks like a television antenna extending up from it. Around the clovers, a broken(cut) line forms a broken circle. Beyond that, the fringes of the cookie is slightly ridged, serving both as visual frame for the decorative center and as a way of grasping the cookie with comparative ease.

   The Oreo has skilled some name changes over the past 105 years. When they were first introduced in 1912, they were known because the Oreo Biscuit (we'll get to why a touch later). Then in 1921, the cookie embraced its shape and was renamed the Oreo Sandwich. In 1937, the name was changed again. This time they took a high-brow turn and assumed the name, Oreo Crème Sandwich. Well, they certainly sound fancier, right? The final name change (for now) came in 1974 when the cookie became referred to as the Oreo Chocolate Sandwich Cookie, Oreo for brief.

  

The scattering of name changes isn't the only inconsistency with the iconic brand. The rumors surrounding the particular name also are a jumble. According to a Time article, it is possible the name Oreo came from "or" the French word for gold, and coincidentally the original package color. Thought Co also sheds some light on the naming process. They say "Oreo" is Greek for mountain, the original shape of the cookie, or that it's as simple as combining "re" from cream and therefore the two "os" in chocolate.
