This tattovertising effort, developed by Colenso BBDO, also enters bathrooms, just like those washroom efforts(see the links given below the post).
They placed stickers of tattoos in bathroom and changing room mirrors throughout the city. People could line the tattoos up in the mirror to give the impression that they were actually on their skin.
