These nameless, smiling faces are always nice to us. They never fail to make our day just a little bit happier.

Coca-cola, the brand devoted to happiness, felt it was time to return the favor.

Coke wanted to give them the "thank you" that mattered the most, the ones with their names on it. For the happiest thank you is the one with your name on it.

We sought out several people who fit the profile above, and worked out a plan with those whose lives they've touched. We wanted to give them a very sincere thank you for all they do.
