This ad is displayed by The Body Shop. If the words are not legible, they say." There are 3 billion women who don't look like supermodels and only 8 do. It counteracts the hegemonic image of attractiveness and emaciated thinness portrayed by the media and men today. Media has a fixed image of thin and sexy women being displayed on every magazine cover page and in every commercial to get their point accross. An ideal image of a woman to a man is a slender body with a perfect figure.
This ad has an appeal to popularity as they have used a barbie doll to convey the above mentioned message about slender women and their importance to the society.
There is a false analogy as there are no fat barbie dolls existing in the market at present.
There is also an inductive fallacy here as he makes a generalization from his experience about 3 billion women not looking like supermodels and only 8 who do. There are no accurate statistics mentioned here neither there is any statistics about 3 billion women in the world.
It is mainly advertiser's exaggeration and his personal opinion in the ad and no concrete facts or details mentioned.
