1981's Raiders of the Lost Ark, which introduced the world to Indiana Jones, is about the search for the Ark of the Covenant, a golden box that can melt the face off anyone who opens it. The box itself is one of cinema's great props,, although, as it turns out, it’s made from simple materials.

CNET is reporting that one lucky person--an unnamed man whose father worked on the film as a pyrotechnician and stage tech--recently took an Ark prop from the original film on the Antiques Roadshow. The box has sat in the man's San Francisco home for years, having been passed down from his father.
