WWF - Day of the Dead
I like these for a few reasons. I like the style. There's an designer/illustrator here in Copenhagen, Tarik Arnautovic, who is pretty well known for his illustrations which are very similar, and I've always been fond of them. I also like the double entendre, and the play with the style of illustration. Finally, I like that they're so simple, and rely on the illustrations and the illustrations alone. But that's just me.
