Bern: International Playground is a quirky new zine from Switzerland. One way to describe it is as an almost scientific catalogue showing samples of graffiti found in a particular environment. The photographic survey presented in this format is the result of more than a decade of research into vandalism occurring on Bern’s S-Bahn trains. From the start, the empty frontcover subtly evokes the concept within as the zine concentrates on the often overlooked margins.
