The iconic smiley was not invented by Forrest Gump:

The badge or button was created by [according to Wikipedia] an American commercial artist Harvey Ball in 1963 for a life insurance company to boost morale. He was paid $45 for his ten minutes work and does not receive royalties for creating a massive symbol of popular culture. Bummer ☹
The design is so simple it’s certain that similar versions were produced before this time, but Ball’s version became the most iconic.
 

First use of the happy face in a campaign for the film Lili in 1953.

My daughter started Kindergarten today and appropriately her name is Lili on her birth certificate. Before she left the hospital we changed the spelling to Lily with a Y as we thought she would end up having to spell out her name her whole life. Turns out there are many versions of the name so she has to anyway and, like the smiley face, its proven very popular. So she’s one of a few.

Anway she had a nice day and we all put on our brave smiley faces
[just not these relics of the 1980’s. ]
