Question

The painting blank is an example of a political work of art

Answer 1

Assuming the painting "Blank" you are talking about is made by Yves Klein, I would say it has a oppression point of view coming through. The black boarders on the canvas show that the inside in being oppressed by not being able to go off the canvas. This may be a way of saying oppression of a religion, gender or Race. Most likely, Race.
