"To whoever finds this card…

This postcard is a work of art.

You have three options:

1. Leave the card where you found it for someone else to find.
2. Take it home and stick it onto your mirror as a daily compliment to yourself.
3. Give it to somebody else and see how it will put a smile on their face."

I left this postcard on the mirror in the hall of my building this morning.

*** Update: a few hours later the card was gone ***
