If you help me win this thing, then PM me your address and I can post you some chocolate (I live in Switzerland).
Basically it's a contest to win tickets to a festival. You can cast three votes a day, all for the same picture if you're so inclined. Contest ends on Friday at midnight.
You have to like the Cardinal Page (beer company), but you can unlike it once the contest ends.
You also have to "accept" the app, but it doesn't post anything on your behalf.

Once you're in, scroll down to "Zürich Open Air and find the picture of people stacked in a pyramid, seen at the bottom left:
Click on the picture, then click on the vote button in the lower left corner.
As said, you can vote three times a day.
IMPORTANT: After the third vote, a little interface will pop up with stuff in german. Just hit the X in the upper right corner, otherwise it will post what you voted on your wall.
Thanks in advance.
