There is a smiling face on the yellow badge. Which company is it?

The original inventor of this world-famous symbol was Harvey Bauer, an employee of American public relations company, but luck didn't come to him. In 1963, he drew the first "yellow smiling face" pattern for a customer of an insurance company and earned only $45. This is also the only income that "Yellow Smiling Face" brings him.

The people who made the "yellow smiling face" pattern "famous" and made a fortune were Spanish brothers. They opened a novelty store, registered a trademark with a "yellow smiling face" pattern, and printed this logo on every product in the store with the slogan "Have a nice day".

The "yellow smiling face" soon swept the United States and spread all over the world. In 1980s, Spanish brothers set up the world's first "one-dollar express" store, continued to sell products printed with "yellow smiling face", and continued to develop chain stores. In 2000, they sold the "One Yuan Express" chain store to "One Yuan Tree Store Company" for 50 million dollars.
