If I sort out 20 Spaniards from different provinces and regions, you wouldn't guess if they were Spaniards, French, South Germans, North/South Italians or even Irish.
Yeah, and some also look Moorish, middle eastern, Sephardic, etc. too. Not a big surprise when you learn about the migrations that happened in Spain during the past 2000 years or so. We are a mixed bunch.
