"Mae West", by: Salvador Dali, looks like a lady’s face but the eyes look like two paintings, the nose looks like a table with a diamond on it and the hair looks like curtains.
"Human Condition", by: Rene Magritte, looks like you are looking in the window but half of it is a painting of the outside. But the painting is on an easel and you can hardly see it. It just looks like you are looking at a window.
