There are many common features between surrealist artists and painters. These include familiar objects that have been slightly changed, mysterious objects, and optical illusions.
–familiar objects that have been slightly changed
René Margritte painted a picture of boots that changed into feet once they reach the ground. At first glance, this pair of boots appears ordinary but it soon changes into something strangely “surreal.”
Two more paintings by René Margritte depict mysterious objects. In “son of Man,” Margritte painted an apple over a mans face. In “Not to be Reproduced,” he painted a man looking to a mirror but we see only the back of his head. (both in reality and in the reflection.
Salvador Dali also dabbled in optical illusions. “Apparition of face, and fruit dish on a beach” can be interpreted as either a bowl of fruit, a lady’s face or even a dog.
