This very famous painting made by Pablo Picasso is named Girl Before a Mirror. The author has painted it in 1932. Picasso was a part of the artistic movement which was called Modernism. This painting was made during his period of cubism. Modernism as such rejected traditions and the works were quite surrealistic.
The girl on the canvas is looking at her reflection in the framed mirror. This reflection is actually the darker version of herself. The form of the girl is broken apart by the geometrical influence of cubism.
