The faces of these girls reminds me of how surprised I was that the mix of faces on a crowded sidewalk in Moscow looked so "American". In the rest of Europe it's different. English crowds look English, Germans look German, etc. When you travel enough you can frequently ID a nationality of someone at an airport by sight, before they open their mouth and you hear the language. Not always but very often.
That thought recalls the observation of de Tocqueville that the two most similar but widely separated peoples on Earth were Americans and Russians. The comment was always a puzzle till I saw (I think) what he meant.
