Everywhere you look, you will see signs. Informative signs, warning signs, advertising signs, protestation signs, decorative signs... So many of them convey either a mixed message, or no message at all! Some you see everyday, without knowing it, until one fine day you actually notice they are here.
Someone has something to say, and maybe we should pay attention to it, it might enlighten us.
Now, one of my favourites is "Transporte and tourismo". If you are going around Brazil and you don't know where to go next, you could just pick a place for it's name: " Don't touch me", or "Foamy", or "Deep Passage". Very inspiring.
