Basquiat's sisters file lawsuit against Christie's over authentication row

The sisters of Jean-Michel Basquiat have filed a $1m lawsuit against Christie's, claiming the auction house failed to authenticate many of the works consigned in an upcoming sale in New York.

Dustheads is Basquiat's most valuable work, selling for $48.8m in May 2013

The sisters state just seven of the works, drawn from the collection of Basquiat's ex-girlfriend Alexis Adler, were submitted to the artist's estate to be authenticated - despite Christie's using the estate's logo on promotional material.

Allegedly Christie's also included a notice confirming the 50-strong collection of pieces were all authenticated, a claim the Basquiat sisters firmly dispute.
