Some really great advertisements

The other day, I received these very creative advertisements through email. I thought they are really sharing material types. So here are few of them:

By Mumbai Police. Replace yolk with brain matter,
and the message hits you hard.

What else can I say?

By Seagram, asking drivers to chose between
either of the two. It's simplicity is something
which I really liked.

Nice and soft!

For a karate school.

To me contrasting is one of the better techniques of
drawing out a message. But over here this was taken
to another level.

Do you need a caption for this one?
