Who is communicating?
The people who are comunicating are the owners of N.K. Fairbank Company, that have recently developed a new type if soap called "Fairy Soap".
What about Who?
the N.K.Company are saying that "Black" people are not as clean as "White" people, because they dont use the same type of soap, and because "Black" people can't afford buying the soap.
Why is it that Way?
N.K. Company are saying that black people are not as clean as white people because at the time, black people were not able to buy suck soap because of the cost of it.
Because of these type of ads, people think that black people are never clean, and poor.
