The big 7-3.

Today, Nov. 20, Queen Elizabeth II and Prince Philip celebrated their 73rd wedding anniversary. Amid the wave of well wishes, the royal couple received a very special card from their great-grandchildren, Prince George, Princess Charlotte, and Prince Louis.

The anniversary card even featured in the Royal Family's official anniversary portrait. But now, as shared by Prince William and Duchess Kate, there's a better look at the Cambridge children's card.

Beside the original anniversary picture, Kensington Palace greeted the Queen and the Duke of Edinburgh with another image offering a look at the lovingly-made card.

A future in the arts for George, 7, Charlotte, 5, or Louis, 2, perhaps? According to People, the grandkids call the Queen "Gan-Gan," and it's possible they may have referred to her as such in the card.

"Wishing a very happy wedding anniversary to Her Majesty The Queen and His Royal Highness The Duke of Edinburgh!" the Duke and Duchess of Cambridge added on the Twitter post.
