Is it even possible to fit one tree at the top of the world, two robins, three polar bears, four toys, five moonbeams, six fairies, seven owls, eight reindeer, nine penguins, ten mice, eleven wish moths and twelve stars on to one little piece of paper. Why, yes it is! We even managed to pop Father Christmas in there too. 

This year's letterhead, released by The Polar Post Office, depicts The Magic Twelve - but can you spot them all?
