Artwork from collapsed investment bank Lehman Brothers and other memorabilia have fetched £1.6m at auction.

The firm’s administrator, PricewaterhouseCoopers (PwC), ordered the sale at Christie’s in London to raise funds for the bank’s creditors.

Gary Hume’s Madonna realised £73,250, and a sign which adorned its offices in Canary Wharf sold for £42,050.

The auction came days after the second anniversary of the bankruptcy which was the biggest in US corporate history.

‘Optimum return’

More than 1,100 bidders signed up for the sale which lasted more than six hours and made £1,641,613, exceeding pre-sale estimates, Christie’s said.

Among the highlights was a commemorative plaque from the opening of Lehman’s Canary Wharf office in 2004 by then-chancellor Gordon Brown.
