This Little Prince and the Fox Postcard was made in France in 2021. The inscription "Le Petit Prince" is golden in colour and the French quote "On ne voit bien qu’avec le cœur. L’essentiel est invisible aux yeux." is printed on the colourful front. There are also the Little Prince and the fox after the Little Prince tamed it. On the back, the English translation "It is only with the heart that one can see rightly. What is essential is invisible to the eye." is printed in black and white. We see the Little Prince standing alone on his own planet.
 
The French quote originates from:
“Adieu, dit le renard. Voici mon secret. Il est très simple : on ne voit bien qu’avec le cœur. L’essentiel est invisible pour les yeux.”
 
“‘Goodbye’,  said the fox. ‘And now here is my secret, a very simple secret: It is only with the heart that one can see rightly; what is essential is invisible to the eye.’” - Antoine de Saint-Exupéry, “The Little Prince”
 
Here are two other Little Prince Postcards: The Little Prince and the Air Balloon Postcard & The Little Prince Postcard.
