I received this reply last year when I had written Grand Duke Henri to express my condolence on the death of his aunt, Princess Marie-Gabrielle of Luxembourg. Marie-Gabrielle was the sister of Grand Duke Jean and daugther of Grand Duchess Charlotte.
This is the 2nd mourning reply I have received from the Luxembourg Royals. I had previously written following the death of Princess Alix, who was Princess Marie-Gabrielle's sister. That reply was from Grand Duke Jean and written on slightly different stationary.
The envelope was a special one. It features black edging for mourning. The inside of the envelope is lined with black tissue paper. You can find the the envelope here along with the standard envelope.
Inside was the usual sort of flat card. This has the same black edging as the envelope.
His Royal Highness the Grand Duke of Luxembourg very much appreciated your message of sympathy on the passing of Her Royal Highness Princess Marie-Gabrielle of Luxembourg.
His Royal Highness would like to convey to you His sincerest thanks.
