Answer
"Balloon Dog (Orange)" by Jeff Koons sold for a record-breaking US$58.4 million at auction in 2013. This monumental sculpture, crafted from high-chromium stainless steel with a translucent orange coating, embodies Koons' signature exploration of popular culture and childhood nostalgia. Its inflated form and vibrant color evoke a sense of playful whimsy, while its mirror-like surface invites viewers to contemplate their own reflections and the nature of art itself.
