Years ago my family and I took a cruise that stopped at a few Carebbean island (Bahamas, US Virgin Islands and Saint Martin).
When we arrived at Sant Martin we decided to go on a tour from the Island. The funny part is that the Island is divided into Two. You might remember this island for it's famous airport: Google "Princess Juliana Airport"
While the Dutch side is a Constituent country the Northern French side is part of France. Funny thing is that calling to Paris from the North Side(French) is not considered an International call while calling the Dutch Neighbors it is
Anyways, so when the cruise arrived at this island, it docked at the Dutch side and we hired a tour the cruise staff offered us to visit both parts of the islands. When the tour guide arrived he gave us Dutch Side car plates for free (One per family) And in the northern side i found a flea market and my girlfriend who speaks a little French help me out to buy a French side licence plate por 12€ (Euros are used in the northern side of the islands instead of US Dollars like the south side)
So here are both the plates i brought from my journey:
