The Puppy (1992) by Jeff Koons engages past and present. This 12-foot flowered sculpture, formed from a stainless-steel structure and designed with sophisticated computer modeling, references 18th-century formal gardens. A West Highland terrier—originally a carved wooden sculpture—Puppy combines the most saccharine of iconography—flowers and puppies—in a monument to the sentimental.
