Zone de Sensibilité Picturale Immatérielle is an artist's book and performance by the French artist Yves Klein. The work involved the sale of documentation of ownership of empty space, taking the form of a receipt, in exchange for gold; if the buyer wished, the piece could then be completed in an elaborate ritual in which the buyer would burn the receipt, and Klein would throw half of the gold into the Seine. The ritual would be performed in the presence of an art critic or distinguished dealer, an art museum director and at least two witnesses.

Performance art is an artwork or art exhibition created through actions executed by the artist or other participants. It may be witnessed live or through documentation, spontaneously developed or written, and is traditionally presented to a public in a fine art context in an interdisciplinary mode. Also known as artistic action, it has been developed through the years as a genre of its own in which art is presented live. It had an important and fundamental role in 20th century avant-garde art.
