LONDON (AP) — Buyers have snapped up modern artworks collected by David Bowie at a London auction, with a painting by Jean-Michel Basquiat selling for more than 7 million pounds ($8.8 million).

The first part of Sotheby's two-part Bowie sale netted 24.3 million pounds ($30.3 million), more than double its pre-sale estimate.

The musician, who died in January aged 69, was a passionate collector of modern art.

The top lot, Basquiat's "Air Power," sold for 7.1 million pounds ($8.8 million).

Frank Auerbach's painting "Head of Gerda Boehm" sold for 3.8 million pounds ($4.7 million), 10 times its estimate and a record for the artist.

Sotheby's said Thursday's auction was a "white glove sale," meaning every lot was sold. Bids came from 47 countries.

More of Bowie's collection is due to be auctioned Friday.
