What if the most known piece of art is not in a museum? It is a logo on a soda bottle. In 1886, a pharmacist in Atlanta, Georgia, invented a new drink. His bookkeeper, Frank Robinson, wrote the name "Coca-Cola" in his everyday cursive handwriting. That handwriting became the logo -- and it has barely changed in over 130 years. Think about that for a moment. Most companies change their logos every few decades to look more modern. Coca-Cola kept the same curvy script because it works. The flowing letters are easy to spot from far away. The red and white colors pop off any background. The design is so distinctive that you can recognize it even in languages you cannot read. Graphic design is a kind of art that combines letters, shapes, and colors to communicate a message. A good logo does something hard. It must be simple enough to remember but unique enough to stand out. Robinson's original handwriting done both. The Coca-Cola logo teaches a lesson about design. Sometimes the most powerful art is not the most complex. It is the art that people see every day and never forget. Studies show that over 94 percent of the world's population recognizes the Coca-Cola logo. No painting, sculpture, or photograph in history comes close to that.
