This photobook essay demands a look back at a painful moment in history, a time of repression, disappearance, and resistance. The exhibition from which this book emerges is perhaps the most popular ever created by an Argentine artist. Over the past decade, it has traveled to more than 100 museums, galleries, universities, schools, and cultural spaces in 20 countries. In the author's words, his project aims to disseminate information and "tell young people a story of violence and absence through emotion, so that they can experience it firsthand and take action to prevent its repetition when the time comes." Author: Marcelo Brodsky.
