This Royal Christmas card from the #RoyalArchives dates from 1929 and shows The Duke and Duchess of York (the future King George VI and Queen Elizabeth, The Queen Mother) and their three-year-old daughter, Princess Elizabeth of York (now The Queen). Last week The Prince of Wales paid thanks to the country’s postal workers, as they worked hard to deliver what is likely to be the biggest festive mailbag in royalmailofficial’s 504 year history. Swipe to see photos from His Royal Highness’s visit to their Delivery Office in Cirencester.
