Musician Sting and wife Trudie Styler are selling more than 200 items from their art collection, previously housed in their former family home in London.
Works by Matisse, Picasso, Gustav Klimt and Ben Nicholson will be offered at auction at Christie's in February, as well as Sting's Steinway piano.
The auction house said the couple had collected the works "with passion and knowledge" over 20 years.
