in celebration of world book day on 5th march, 7UP has teamed up with buenos aires-based artist raul lemesoff in the creation of ‘weapons of mass instruction’, a traveling library that tours argentina in the shape of a tank. the ongoing project, which lemesoff has built upon throughout the last few years, sees a 1979 ford falcon transform into a military-style vehicle, with a rotating upper chamber and pseudo-barrel. although the tank may look militant, it has a very serious function of peace — lemesoff tours through argentina’s urban centers and rural communities, offering free books to anyone interested. around 900 books fit on the car’s built-in shelves, with a varied collection of poetry, novels and biographies.
