On the card you can see the Seven Mile Bridge coming south from Marathon to Key West and was one of the longest bridges at the time it was built. (1982).
It is located in the Florida Keys, a coral cay archipelago located off the southern coast of Florida, forming the southernmost portion of the continental United States.
Whenever I look at this card, it looks like a bunch of light-bulbs had been lined up, lurking from the water.
Three nice stamps here - the George Washington one from 2010, next to whom is Mother Theresa, issued in 2010, commemorating the 100th Anniversary of her Birth, while the third stamp is from 2011, simply titled Jazz.
Thank you very much Jean Pierre!!
