San Marcos, TX.- “The Edge of Time: Photographs of Mexico by Mariana Yampolsky” marks the beginning of the Wittliff Collections twenty-fifth anniversary exhibition schedule at Texas State University-San Marcos. This show featuring works from the permanent holdings runs from May 16th through December 11th, with other celebratory exhibitions to be added in August. “The Edge of Time” exhibition honors Mariana Yampolsky’s role in the Wittliff Collections’ history with nearly 60 silver-gelatin photographs of Mexico she created during the 30-year span of 1964 to 1994. “Reflecting moments,” as she said, “in the lives of people that others perhaps don’t see or don’t value,”
