The decision to close was announced last week, two years after Zerns management placed the 24-acre, 200,000-square-foot commercial space on 1100 East Philadelphia Avenue for sale. Although Zerns' owners had received some queries about the property from potential buyers — some from as far as London, Brazil, and Dubai — management said in a statement that they were looking for a buyer who would be "willing and able to carry on the legacy of Zerns and usher her into a new era."
