A red and gold badge. On the back are stamped the names of two museums: 中国革命博物馆 (China Revolutionary Museum) and 中国历史博物馆 (China Historical Museum). These two museums were combined in 1969, and eventually became the National Museum of China. The badge probably dates to1972. The Needham Research Institute Library holds a book of an exhibition of Cultural Revolution Excavated Artefacts, signed by Guo Moruo.
