Porto and North I

in this card says "Oporto and North has".
in this case, yes, we have! Oporto wine and their wine cellars! one of the most famouse wine in world, the first delimited region for wine in world (since 1756) and a UNESCO World Heritage Site since 2001!
I got this card in an exposition in "Alfândega do Porto" (old place of Oporto Customs).
