4: Jeff koons

Jeff Koons  born in York, Pennsylvania; as a teenager he revered Salvador Dalì,  Koons attended the School of the Art Institute of Chicago and the Maryland Institute College of Art, and studied painting. After college he worked as a Wall Street commodities broker, whilst establishing himself as an artist. He gained recognition in the 1980s, and subsequently set up a studio in a Soho loft on the corner of Houston and Broadway in New York. This had over 30 staff, each assigned to a different aspect of producing his work—in a similar mode to Andy Warhol's Factory (and many Renaissance artists).

Koons' early work was in the form of conceptual sculpture, one of the best-known being Two Ball 50/50 Tank, 1985, consisting of two basket balls floating in water, which half-fills a glass tank. (The influence on Damien Hirst's later work The Physical Impossibility of Death in the Mind of Someone Living—a shark suspended in formaldehyde in a glass tank—is unmistakable.)

Koons then moved on to "Statuary", the large stainless-steel blowups of toys, and then a series "Banality", which culminated in 1988 with Michael Jackson and Bubbles—stated to be the world's largest ceramic—a life-size gold-leaf plated statue of the sitting singer cuddling Bubbles, his pet chimpanzee. (Three years later it sold at Sotheby's New York as Lot 7655 for $5,600,000, trebling Koons' previous sale record.)

I first saw this sculpure in the night at the museum two film and i thought it was just a random piece of cartoon that just happened to be in the film but later i descoverd that it was a real work of art by a contraversial sculptor jeff koons famed for art as well as porn what i enjoyed about this piece in perticular was the fact that it was so simple and contemporary it didnt need a story or a dialoge or a complicated message it simply is what it is a giant balloon dog it dosnt need anything else to make it interesting to look at it still ticks all the boxes of being a good sculpture it is symetrical it has balence ,form and a representative shape it works well big or small ,so i like this piece of art for doing what it says on the tin by being uncomplicated easy on the eye full of wit and for being a giant red balloon dog.
