Napoleon Bonaparte's famous bicorn hat is up for auction and on display next to the chateau where the French general lived when he wasn't leading troops into battle across Europe.
The black felt is a little weathered by age and use, though no one's actually worn the hat since Napoleon's cavalry veterinarian, who received it from the leader as a gift.
Auctioneers are hoping to fetch 500,000 euros ($623,000) for the hat. It is part of a Napoleonic collection belonging to Monaco's royal family, which is distantly related to him.
Also for sale from the collection are dozens of medals, decorative keys, documents, a jeweled sword, a Russian caviar spoon and a bronze eagle that once perched atop a battle flag, complete with bullet holes.
