I think she’s beautiful just as she is.
Any artist, sculptor or designer working with natural copper knows it will change color to the blue-green patina of aged copper and will never stay the color of raw copper once exposed to weather. Any building made with copper for roofing or trim has the same features. Using clear finishes to artificially keep the raw copper look is a recent trend that is not an honest use of the material.
In 1982, four years before the Statue's centennial anniversary, President Ronald Reagan appointed Lee Iacocca, the Chairman of Chrysler Corporation, to head the Statue of Liberty - Ellis Island Foundation. The Foundation was created to lead the private sector effort and raise the funds for the renovation and preservation of the Statue for its centennial in 1986. The Foundation worked with the National Park Service to plan, oversee, and implement this restoration.Workers repaired holes in the copper skin and removed layers of paint from the interior of the copper skin and internal iron structure. They replaced the rusting iron armature bars (which joined the copper skin to the Statue's internal skeleton) with stainless steel bars. The flame and upper portion of the torch had been severely damaged by water and was replaced with an exact replica of Bartholdi's original torch. The torch was gilded according to Bartholdi's original plans.
The restoration was completed in 1986 and the Statue's centennial was celebrated on July 4 with fireworks and fanfare. On July 5th, a new Statue of Liberty exhibit opened in the base of the pedestal.
So do I! Just leave her as she is!
