The Battleship North Carolina has an extensive collection of World War II artifacts, documents, and memorabilia associated with the USS North Carolina. Among the thousands of items is a map depicting the island of Iwo Jima during WWII. The map is a three dimensional relief map used for training purposes.
Rubber has what conservators refer to as an "inherent vice", meaning that the rubber the map is made from is causing its own deterioration. Rubber requires very special conservation considerations. The map underwent conservation at the conservation lab to insure its long term survival for future study and appreciation. It was placed into a custom made exhibit case that has an oxygen free atmosphere with special UV filters to prevent further deterioration.
East Carolina University hosted a public viewing of the map at Joyner Library after its completion in 2011. It was the 66th anniversary of the landing at Iwo Jima in 1945. Presentations by Department of History faculty and the Joyner Library special collections staff were also made.
