American Artifacts visited the Library of Congress to learn about a new exhibit, "The Last Full Measure: Civil War Photographs from the Liljenquist Family." We spoke with Tom Liljenquist, who explains how – fifteen years ago – his family started collecting photographs of ordinary Union and Confederate soldiers. In 2010, the family donated more than 700 of these ambrotypes and tintypes to the Library of Congress.
