Casey Mallinckrodt, objects conservator at the Atheneum, said this is possibly the first time the statue, which has endured rain, hail, sleet, snow and increasingly polluted air for 128 years, has been cleaned. “In the ’30s there is documentation of a correspondence regarding the potential treatment of the statue, but record keeping was very poor at that time, so it may or may not have been treated,” she said.
