GRENOBLE A lock of Louis XVI's hair, cut from the French king's head just after his execution in 1793, was sold at auction on Saturday for 31,000 French francs ($5,636). An anonymous royalist bought the hair after a brisk but shortlived round of bidding. A spokeswoman at the sales house in the southeastern French city of Grenoble said the lock was originally picked up by a drummer present when Louis XVI was guillotined in central Paris in the aftermath of the French Revolution.
