Read the title of the text, the introduction and the subheadings and look at the pictures. What do you expect to read about?

I expect to read about three kinds of art which are unusual and which differ from the normally accepted idea of art (Я ожидаю прочитать о трех видах искусства, которые необычны, и которые отличаются от стандартно принятой идее об искусстве).
