Wearing a mask and gloves to protect fragile documents, an archivist opens one of the thousands of books of photographs held by the Historical Archives of the National Police. The Guatemalans pictured inside were all detained or arrested by the National Police during the country’s long civil war. Many of their fates remain unknown. Sometimes, visitors to the archive—or the archivists themselves—will turn a page and recognize a friend or relative not seen in decades. Image by Lynn Johnson. Guatemala, 2017.
