George Michael died aged 53, according to his publicist on 25 December 2016.
Every single artwork was sold at last night's competitive auction, which Christie's said was "a tribute to both George Michael's eye for contemporary art and the depth of feeling for an artist whose songbook of classic tracks defined an era".
The energy was palpable in a packed saleroom at King Street, and among the many bidding online, on the phones and via a live link from Christie's NY saleroom.

Michael, who died in December 2016 aged 53, was a keen collector of works by the Young British Art movement and was friends with numerous artists. It attracted bidders from 27 countries across five continents, with competitive bidding taking place in London and via simulcast from NY.

The highest selling item was Damien Hirst's The Incomplete Truth, part of his 2006 "Natural History" series, in which formaldehyde-suspended animals and organs take centre stage.
Other sold lots include works by Bridget Riley and Tracey Emin, plus three pieces by Irish-born Michael Craig-Martin that detail Michael's public arrest for "lewd behavior" in a Beverly Hills park back in 1998.
Another of Hirst's works - Saint Sebastian, Exquisite Pain, a representation of the death of the Christian martyr using a bull encased in formaldehyde - sold for £875,250 at the London auction.
A life-size bronze gorilla by Angus Fairhurst that used to sit in Michael's garden also went under the hammer, fetching £118,750.
Cristian Albu, of Christie's, revealed George Michael's relationship with Emin had a "tricky" start.
The collection toured New York, Los Angeles, Hong Kong, Shanghai before landing in London.
