There have been suggestions that Ethiopians are rather separate from the Bantu Africans and may have some middle-eastern admixture. In any case, they have a distinctive appearance. Anna Getaneh, Ethiopian supermodel:
On darker-skinned models, below is quite an old photograph of a girl modelling an Italian woollen suit. I always assumed she was African but maybe she was a dark southern Italian.
Does anybody recognise her? I have had good luck with this sort of query recently, so maybe I will get lucky again.
