An electric chair and other artifacts of Ohio's darker history are featured in an upcoming exhibit that will restrict younger visitors.
"Controversy: Pieces You Don't Normally See" opens April 1 at the Ohio Historical Center in Columbus. Children under 18 will not be allowed in unless accompanied by an adult.
The show also will include a 19th century wooden cage for restraining Ohio mental patients, an aluminum mitt that once kept children from sucking their thumbs and a 1920s Ku Klux Klan hooded robe.
The Columbus Dispatch reports that the electric chair _ nicknamed "Old Sparky" _ hasn't been on view publicly since tours of the old Ohio Penitentiary stopped 80 years ago. The chair was last used for an execution in 1963.
