Vanished Kingdoms: The Wulsin Photographs of Tibet, China, and Mongolia, 1921-1925 is an exhibit of 39 compelling color images of rare colored lantern slides taken by two young American explorers, Janet E. and Frederick R. Wulsin, Jr., from the collections of the Peabody Museum of Archaeology and Ethnology, Harvard University.

Janet was one of the first American women explorers to reach western China, Inner Mongolia, and Tibet. Together they produced this series of superb photographs of the Ta'er, Labuleng and Zhuoni lamaseries, religious ceremonies, and landscapes they encountered during their expedition for the National Geographic Society in 1923. Shown publicly for the first time, this traveling exhibit is organized by PEM in conjunction with the Peabody Museum of Archaeology and Ethnology, Harvard University.

Vanished Kingdoms showcases 39 stunning prints, on loan from the Frederick R. Wulsin photographic collection at the Peabody Museum of Archaeology and Ethnology, Harvard University. Peabody Essex Museum (PEM) commissioned renowned digital artist Fernando Azevedo to create the archival inkjet prints, which reveal, in large scale, the intricately detailed interiors as well as breathtaking landscapes found in the original hand-colored lantern slides.
