Sale of 16th century torture devices to benefit Amnesty International

"Shame masks," "tongue tearers," and "witch-hunters" are among the 250 items of torture dating to the 16th century to be auctioned by New York's Guernsey's auction house. The items, from a privately-owned collection, will be sold, with the proceeds going to "Amnesty International and other organizations committed to preventing torture."

The collection of torture devices and books has passed from owner to owner over the years, and even was displayed in 1893 at the Chicago World's Fair. The current owner has not been identified by the auctioneers.
