Table top sale

A Gladstone Table is being sold at Bonham's in London, as part of a fascinating collection of fossils and minerals from the estate of Professor Gordon Walkden. He was Emeritus Professor of Geology at the University of Aberdeen, referred to by some as Aberdeenshire’s answer to Indiana Jones. The circular top is centred by stalactite flowstone of the Kents Cavern type and eight radially arranged and unusually large plaquettes of various Devon marbles. It is being sold as part of the Collections Sale, Bonhams Knightsbridge, on 28 June. It has an estimate of £5,000-8,000. www.bonhams.com
