Inspired by Marcel Duchamp's ready-mades, Koons's early works consisted of actual toys and houshold appliances backed with mirrors and enclosed in plastic vitrines. He has often produced works in series, including "Statuary" (1986), stainless-steel versions of novelty-item sculptures; "Banality" (1988), sculptures resembling large-size dime-store gimcracks, notably a life-sized gold-plated porcelain figure of pop star Michael Jackson and his pet chimpanzee; "Made in Heaven" (1989-91), mainly sexually explicit paintings, sculpture, and photographs of himself and Italian porn star "La Cicciolina," whom he subsequently married and soon divorced; "Celebration" (1994-2006), large paintings and sculptures of toys, food, and other things that delight children, among them huge smooth-surfaced stainless-steel balloon animals in deeply saturated colors, e.g., his 14-ft-high (4-m) Rabbit (2003); and "Hulk Elvis" (2007), brilliantly colored, collagelike oil paintings, many featuring cartoon superheroes. One of his best-known sculptures, the monumental Puppy (1992), is a 43-ft-high (13-m) seated terrier pup blanketed with thousands of flowering plants.
Koons makes a point of avoiding all traces of the artist's hand. Much of his work is conceived on computer and executed by squads of craftsmen. Something in Koons's works, perhaps their appeal to mass culture or the ease with which they can be understood, has struck a chord with collectors, and his works have fetched multimillion-dollar prices in galleries and and set auction records. His stainless-steel Hanging Heart (1994-2006) was sold at auction in 2007 for $23.6 million.
