Objects always played a crucial role in Surrealist exhibitions. They would blur the boundaries between place of exhibition and place of experience, and leave the observer in the dark about whether the thing he was confronted with three- dimensionally and physically was a work of art or something to be used, touched, or changed. As a matter of fact, the interplay of opposites and the shift of reality that hints at the unconscious and dreamlike particularly manifest themselves in the Surrealists’ strange and bizarre objects and sculptures. Numerous objects have an everyday origin and were worked on and transformed until their meaning changed into something strange. The iconic, L’Introuvable by Marcel Mariën perfectly epitomizes this process.
