Puerto Cortes is Honduras's main sea port and it is considered the most important seaport in Central America.
the back of the card says: "Vista Nocturna del Puente Sobre la laguna De Alvarado, Puerto Cortes"
I guess it has to something with a night view...of the De Alvadaro laguna..
Unfortunately, i couldnt really come across any worthwhile information about it, without sounding like a travel agent's who wants to sell you something....
