Exhibition catalogue comprising a selection of never before published photographs taken by Antonio Quintana (Chile 1904-1972), which were rescued through the investigative work of the Archivo Patrimonial de la USACH. His widow, Enriqueta Silva, donated more than 3,000 images to the former Universidad Técnica del Estado, now the Universidad de Santiago, shortly after the photographer's early death in 1972, at the age of 68, as a result of a cerebral vascular infarction. Only a small part of the file that protects the Archivo Patrimonial de la Universidad, today it is recovered in an exhibition and in a book that includes 100 photos, along with a website where anyone can see the complete digitized material.
