How do the pictures and map …

The pictures and maps on the wall are contrasted against the stiflingly dreadful environment in which the children live to bring out the futility of their education in a slum. The worlds that the children get a glimpse of can only remain a fantastical impossibility for them because they do not have access to the most basic amenities in life such as food, hygiene and clothing. Thus, the maps and the pictures might just as well be fantastical realms for these children they read about.

The map of the world on the classroom walls is drawn in accordance with the will of the powerlords. This world is not even remotely related to the world of the dirty slums. The world depicted in the pictures that decorate the walls holds a stark contrast with the world of the underfed poverty stricken slum children who live in cramped dark holes. The pictures suggest beauty, well-being and prosperity. So there is no connection whatsoever between the map of the civilized world to that of the world of the children.
