Balloon Dog is a series of sculptures by the American artist Jeff Koons. There are different versions of this sculpture, made between 1994 and 2000, with each having a different color: blue, magenta, yellow, orange and red. All versions of the sculpture are made of stainless steel, using different coatings to produce the different colors.
Jeff Koons is as much the artist behind this as Elon Musk is the founder of Tesla
