caption: 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 <PERSON> 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 <PERSON>. Guatemala, 2017.
