An eagle-eyed hotel worker noticed something odd about a Winston Churchill portrait before discovering the original was stolen and replaced with a replica.
The portrait, taken by photographer Yousuf Karsh in 1941, has gone missing from the Château Laurier hotel in Ottawa, Canada, but for exactly how long remains a mystery.
Last week, a staff member spotted that the frame didn't match those of the other five portraits in the room, which were captured by the same photographer.
