There are many other purposes of art. Another goal of art can be the author is trying to get by a series of commentary. Commentary just means that the artist made the painting or artwork in order to communicate to the viewer. It can be a specific idea or broad, even of a world view. This picture has commentary of social equality and freedom. This artwork was made during the civil rights movement to show that colored people deserve freedom in the US just like whites. They eventually got those rights, which were needed, but the other commentary in this is the idea of freedom which is represented by the American flag. The US has the most amount of freedom than any other country. The people of the US also have a lot of rights that our guaranteed which is very nice. Not a lot of citizens across the world of other countries have that.
