Jeff Koons for H & M
Anyone who's ever seen Jeff Koons' work in person knows he does things in a big, big way. Like the time he wrapped the H & M flagship store in pictures of his balloon dog sculpture. Not only did the image make it on to a handbag, but on the store's shopping bag as well, making it an amazing piece of portable art work.
On a totally different note, if you ever need someone to make balloon animals for a party, this guy is amazing.
