see edit in the first post. Anatomy sometimes can be misleading in Greek pottery. Masks used in Greek drama bore sometimes much resemblance to what we would call black African characteristics but they were only caricatures of faces and had nothing to do with racial determination. In low res images and from unfavorable angles, sometimes it is very difficult to tell. It is not that much the nose and certainly not the color but mainly the hair in this image that points to the person depicted being a black African.

I found it in a random, silly site about black Africans appearing in Greek pottery -I just image googled and saw it- but the link points to it being someplace in wikicommons, so probably it is also used in some wikipedia article.
