In 1926 Magritte produced the first of many surrealist paintings. Magritte, like Dali, specialized in oneric surrealism - recognizable scenes metamorphosed into dream images, and in some cases nightmares; however, unlike Dali's paintings that illustrated the consistency of objects, Magritte juxtaposed ordinary objects in extraordinary ways. Magritte also played with the logic and placement of objects in his paintings. For instance, most recognizable painting The Treachery (or Perfidy) of Imagaes features a large pipe as the object of the composition, under the pipe are the words "This is not a pipe". Magritte's purpose for this painting was two fold: first, he had a since of humour (another similarity between him and Dali); second, he wanted to illustrate the difference between expectations and reality. The focus of the painting is a pipe, but the painting was created with canvas, paint, and additional painting tools. the painting is a piece of art, the painting is not a pipe.
