In the basement of Alberta's Vermilion Heritage Museum, atop a reinforced floor, sits an old safe that had never been opened-- until now. A man named Stephen Mills was on vacation with his family, and was taking a tour of the museum recently when the safe caught his eye. He tells the CBC, "I put in 20-40-60, three times left, one time right." And then the safe opened. A cloud of dust billowed out, but otherwise all that was inside were a few hotel documents, including a pad of restaurant orders and a 1977 pay stub for $6 and change. Previously, experts said it would likely never be opened. Museum officials have now covered the locking mechanism with tape and left the door ajar, fearing it could lock up again.
