Every December an envelope bearing a stamp from the North Pole would arrive for J.R.R. Tolkien’s children. Inside would be a letter in a strange, spidery handwriting and a beautiful colored drawing or painting. The letters were from Father Christmas. They told wonderful tales of life at the North Pole: how the reindeer got loose and scattered presents all over the place; how the accident-prone North Polar Bear climbed the North Pole and fell through the roof of Father Christmas’s house into the dining room; how he broke the Moon into four pieces and made the Man in it fall into the back garden; how there were wars with the troublesome horde of goblins who lived in the caves beneath the house, and many more.
