THREAD: The tradition of The Royal Christmas Card goes back over 100 years, sending cards to charities, staff, personal friends and notable people who they've come into contact with during the year. Here are a collection of some of our favourites!

As her grandmother & grandfather did in WWI, Princess Elizabeth sent a Christmas card to the Grenadier Guards during WWII
As their children grew up & had families of their own, Elizabeth & Philip would include their grandchildren on several of their cards.
