This is the same as the "racist game" topic, if people don't stop coming to their own conclusions when a black person is used, or in some cases a monster that kind of looks like a cartoon from back in the day that was derogatory to black people, then racism will still be rife.
It's a black girl and a white girl posing for an advertisement, that's it.
I don't think this particular one is in Amsterdam.
The one I saw was in the Kalverstraat, and this does not look like that street at all.
It's probably somewhere in the Netherlands as you said though, going by the Dutch words on the buildings.
