This reply arrived last week. I had written to Prince William & Princess Kate last September following the death of Queen Elizabeth II. This is the 2nd reply I have received for the death of Queen Elizabeth.
The envelope was the standard from the couple. I've recently decided to repeat myself one hundred times about standard envelopes. We explain details on their envelope here. And you can find information on the standard postmark here.
Inside is a folded card. This is not the couple's usually reply. But we have seen this before for their reply for Prince Philip's Death. (The one big difference was the reply for Prince Philip was printed on a more expensive glossy paper.)
The front of the card features the couple's monograms. The couple are still using the coronets of the "Children of the Heir". We have yet to see the couple switch over to the Crown of the Heir on any of their stationary or other things.
The back of the card features a credit to the photographer, "Paul Hackett/PA Images".
The black border is for mourning. And is an old Victorian-era tradition, that I find especially lovely. While some royals use this black mourning edging, it's not required that royals use it.
The Prince and Princess of Wales would like to thank you for the kind words you sent following the death of Her Majesty The Queen.
Their Royal Highnesses have been extremely touched by the very thoughtful messages of condolence that they have received during this time.
They will deeply miss Her Majesty, who played such an important part of both of their lives, but so appreciate your message which has provided them with a great deal of comfort.
