In the 2015 letter, Father Christmas introduces children to Sir Bastian the only penguin to live at The North Pole, and explains how he helped to save Christmas when a lost polar bear accidentally stumbled into the wrapping hall!
Letters are signed by Father Christmas, then hand-addressed, stamped, and franked by the elves. The finishing touch is added when the elves emboss the letter with the one word that every child wants to hear in the build-up to Christmas – that they have been NICE.
