Pin given to Margaret Gruenbaum in the Theresienstadt concentration camp by a fellow inmate who worked with her in the camp workshop. Margaret worked in the art studio making artificial flowers, toys, and stage sets for various Terezin productions. Her job in the workshop may have saved her family from deportation to Auschwitz death camp. When the family received orders for deportation in the autumn of 1944, Margaret was able to help her boss, the Dutch artist, Josef Spier, convince a camp guard that her work - creating teddy bears and others toys for Germans for the Christmas season - was important enough to keep her, and her children, 14 year old Marietta, and 12 year old Michael, in Terezin. The guard removed them from the transport list. The Gruenbaum family were Czech Jews who had been deported from Prague to Theresienstadt on November 20, 1942. They were liberated from Theresienstadt on May 8, 1945, by the Soviet Army.
