With the idea of drawing simple faces on many objects and patterns (especially on natural patterns, such as the sun and the moon), you can find patterns that are very similar to the grinning images we see in ancient hieroglyphics today. You can also see in the movie Bye-bye Birds that dick van dyke was painting this happy smiling face when he sang the song "Pretend to be a Happy Face".

The combination of bright yellow, rough design and badge (or bumper sticker), coupled with the passage of time, has made this happy face a popular pattern, and even Disney is eager to proudly announce that it was designed by them.

In the past many years, some companies have tried to register happy smiles as their own trademarks. In France, there is a company called Smiley Licensing Corporation, which successfully got some companies to pay them license fees instead of suing them, thus obtaining the right to use this smiling face. But around the world, other companies have successfully challenged companies that claim to have a happy smile in law. At least in the United States, the "sign" of a happy smiling face is an open tender to decide who can use it.

There are several contradictory opinions about the origin of happy smiling face, but here I want to talk about one of the opinions recognized by historians. The whole story sounds true, and I believe it is true.
