Like many other Jewish children during Nazi occupation in Europe, Anne Frank gave away her toys before going into hiding with her family. Eventually, she was sent to the Bergen-Belsen concentration camp where she died of typhus. The diary Anne kept is now regarded as one of the most widely-read pieces of Holocaust literature.

Anne gave the family cat and several toys, including her marbles, a tea set, and a book, to one of her non-Jewish childhood friends, Toosje Kupers, because she feared they would “end up in the wrong hands.” Kupers, who is now 83 years old, found the items last year while moving and decided to give them to the Anne Frank House Museum. The toys are on display as part of an exhibit at the Kunsthal Art Gallery in Rotterdam: The Second World War in 100 Objects is on view now through May 5, 2014.
