Bitches, Bimbos and Ballbreakers

I read this book in one day (Bitches Bimbos and Ballbreakers by the Guerrilla Girls)
It is very entertaining and funny and I did not even realise that there is always some sort of female stereotype that women are going to have to live up to...or live down.
The Guerrilla Girls posters that sometimes include taking well known 15th century paintings and distorting the faces with a gorillas face, appear in well-known American magazine such as the New York Times and Vogue and protest their part by trying to re-invent the 'F word' (feminism).
Their work uses examples of post-modernism by disregarding graphical distinctions between high and low culture. Their posters probably broke all the rules of posters in the 80s by consisting of bold type with lack of visuals, however, this technique made the viewer uncomfortable, resulting in attention being drawn to the point. (Poynor, 2003, page 157)
Here are some examples of posters that would appear around cities where protests would take place.
