Princess Charlene of Monaco's Birthday (2019)

Today I received a lovely reply from Princess Charlene of Monaco! 

One of the things I most appreciate when receiving an envelope from Monaco is the fact that they use stamps! Prince Albert's father loved stamps and what some of you may not know is that he He oversaw the production of all of Monaco's stamps and opened the Museum of Stamps and Coins.

This particular stamp was made in 2009

Inside features a "normal" reply from Monaco, however, unlike all the other ones I've seen this one is large in height and shorter in width. If this is a new thing Monaco royals are doing, I hope they keep it up. 

The card reads: 

Her Serene Highness Princess Charlene was extremely touched by the kindness shown on the occasion of Her birthday and would like to express Her sincere thanks.
