There are many stories of messages in bottles travelling thousands of miles before being picked up and read, and letters arriving decades after they were posted. But here is a different twist.
Rebecca Cathrine Kaadu Ostenfeld was reportedly surprised when a letter was delivered to the horse farm where she lives with her husband and three children near Búðardalur in the west of Iceland.
Instead of a postal address or a recipient's name, the sender had drawn a map of where they believed the farm to be, together with the following, in English:
"Country: Iceland. City: Búðardalur. Name: A horse farm with an Icelandic/Danish couple and three kids and a lot of sheep!"
The sender had also added a further clue to the intended recipient: "the Danish woman works in a supermarket in Búðardalur."
The letter had been written and sent from the Icelandic capital ReykjavÃk by a tourist who had stayed at the farm but who obviously did not know the address.
And, extraordinarily, it arrived at the right place.
