This presentation discusses the Mexican Revolution, as seen through the camera lens of American photographer Otis A. Aultman. In 2009, El Paso Public Library's Archivist Marta Estrada received a grant from the UNT Libraries to digitize a portion of their Otis Aultman Photograph Collection and add it to The Portal to Texas History. El Paso Public Library's collection on the Portal consists of more than 500 digitized glass plate negative photographs that documents the Mexican Revolution through the eyes of Mr. Aultman, many of which have not been seen for a century.
