The Associated Press reports that Body Worlds, an art workshop in China, has drawn some attention by Chinese, as well as German, media because of the possibility that some of the corpses in the display may have been executed prisoners, as well as corpses that may not have been donated.

The displays, which feature bodies that have been injected with epoxy and silicon, are the creation of Gunther von Hagens, a native German, who has set up shop in Northeastern China.
