Tracey Emin's unmade bed shocked the establishment with its dirty sheets, cigarettes and vodka bottles. She entered it into the Turner prize 15 years ago. While many questioned whether it was art, there can be no doubt that the place where she slept turned Emin into an overnight success - and it helped define an era.
ITV News correspondent Lewis Vaughan Jones reports:
After her win she said: "People close to me find it somewhat repugnant but then art can be like that, people can be like that."
She became as famous for her behaviour as for her creations.
She was once televised saying: "I'm here, I'm drunk, I had a good night out with my friends, I'm leaving now. I want to be with my friends, I want to be with my Mum."
In her London studio she told ITV News she could still be wild but the smoking, sex and chaos have gone.
She is still creating and exhibiting new work.
"I don't know whether this is the beginning of a painting or the end of a painting. It will take 10 years," she said.
The collector Charles Saatchi bought her original bed and is now selling it for around a million pounds. It will probably be sold abroad, and will go to auction this summer.
