A lovely reply arrived today from Monaco. This is my first reply of 2021 and my first Christmas 2020 reply.
The front of the envelope says "Service of HSH The Prince of Monaco" in French. This is used on Prince Albert's mail as well as his sister's, as they don't have their own mark. Princess Charlene has her own, which says "Service of HSH The Princess of Monaco" in a circle with the Monaco Coat of Arms.
The envelope features a special holiday postmark "Meilleurs Voeux," which is French for Best Wishes/Happy New Years. This postmark was stamped on all the mail in Monaco from December 21st, 2020 to January 9th, 2021.
The stamps are to mark the 75th anniversary of the United Nations and were released in October 2020.
What is interesting that this was sent to my old address, and then forwarded. We have known for years that the Monaco Royals have a database in which they store information on people who write or attend events at the Palace. So, they simply pulled my address from the database instead of the envelope.
