Richard Ball, co-owner of an advertising company, designed the Smiley Face back in 1963. Its original intention was to be the symbol of a “friendship campaign” that would be used to help ease the tension following the merger of two insurance companies. Unfortunately the advertising company never trademarked or copyright protected the symbol.
It was later copyrighted along with the words “Have a nice day”.
This example is on the wall of a disused US army building in the city of Wiesbaden, Germany.
Have a nice day 🙂
