NEW YORK (AP) ― Photographs by the wife of imprisoned 2010 Nobel Peace Prize winner Liu Xiaobo will be shown at Columbia University next month.

Beijing artist Liu Xia has been under house arrest since shortly after her husband was awarded the peace prize. Her photos were smuggled out of China just before she was placed under house arrest.

Liu’s works are censored in China. The series of 25 photos depict lifelike dolls in various settings. One shows her husband holding a doll. In another, a tied-up doll sits in front of an open book.

The exhibition runs Feb. 9 to March 1. It will not be shown elsewhere in the U.S.

The Boulogne Museum outside Paris exhibited the photos in the fall.

Liu Xiaobo was sentenced in 2009 to 11 years in prison for urging democratic reform.
