Pieces from David Bowie's private art collection have been shared online ahead before being auctioned off in a November sale expected to reach in excess of £10 million.

The musician was famously elusive, keeping even his battle with cancer a secret until his death in January, days after he had released his final album, Blackstar, on his 69th birthday. But when he did give interviews, he spoke about his passion for art, saying it was the "only thing [he] bought addictively".
