Grey women's prison cotton shirt with the letters Z30D written on the chest in faded black ink. The shirt was worn by Lieutenant Nguyen Thanh Thuy, a former member of the SWAN (a special police force under the Republic of Vietnam), during her 13-year detention in the Z30D re-education prison camp between 1975 and 1988. She took this shirt with her when she was released and relocated to the US through the Ordinary Departure Program (ODP). The PTSD caused by her long imprisonment made her unable to drive for several years because she was triggered by the sound of keys, but she was eventually able to get treatment and overcome the trauma.
