For 7up and its campaign “Feels Good To Be You”, Raul Lemesoff, Buenos Aires-based artist, has designed a tank by thinking it as a “massive weapon of instruction” in order to fight ignorance and spread knowledge. In his tank (an old Ford 1979 Falcon Lemesoff) converted in a library and filled by 900 books, he drives through the streets to offer books freely to passer-by.
