The envelope is the usual sort from the Monaco Royals. The postmark says "Happy Holidays" in French and was used on all outgoing mail in Monaco, December 23rd-31st. The stamp features Ferdinand Magellan and was issued in 2019 to commemorate the 500th Anniversary of the first person to circumnavigate the globe.
The back of the envelope features the couple's joint monogram.
The Christmas card is the same format as past years. The Monaco Royals have some of the nicest replies in terms of quality.
The front features a red border with the couple's joint monogram. It's embossed (raised), so it gives it a lovely feel. In the center is a photo of the Twins. What is especially lovely is the photo is printed on photo paper and then attached to the front of the card, which makes this really high quality.
The photo features the Monaco twins, Crown Prince Jacques and Princess Gabriella. This is their 2nd time appearing solo on the Monaco Royal Family's Christmas Card. One interesting thing this year is the photo has been heavily photoshopped. Personally, I don't feel like the sparkles and little dots of snow really add to the photo. This year's photo was taken by Eric Mathon, a photographer who works for the Palace.
Inside there is another photo, this time by Vanessa Von Zitzewitz. This photo was from last year's Christmas Card. And again has been very heavily photoshopped. As this photo was printed directly on the paper, it isn't as good quality as the front photo. If you look closely around the photo you can see the lines where the cover of the card is embossed.
The other side of the card features a message from the couple along with printed on signatures. The message is written in 3 languages: French, English, and Monégasque.
The card reads:
May the peace and joy of the holidays be with you every day in the New Year! We wish you a Merry Christmas and a wonderful 2020.
Albert de Monaco Charlene de Monaco
The paper has a nice weight to it. And you can't tell from the above photos, but the envelope and card have little sparkles in them.
