"It was difficult to give a saleroom valuation, but an identical mask and hands were sold in 2012 for £3,600, so we decided to offer it with an estimate of £1,500-2,000," the magazine quoted Dan Ponder, an employee of the auction house.
It was reported that a bronze mask and hands in early August were acquired by a foreign collector by phone.
