Christie's

Christie’s is holding a five-day exhibition from September 13-17 in its Paris rooms of selected works from the collection of the famous architect IM Pei which are to be sold across various Impressionist and Modern and Contemporary and 20th century Chinese art auctions in Paris, New York and Hong Kong over the autumn season.

This double-page engraved chart is from an early-17th century pilot book which is another of the highlights from the Mopelia Collection of atlases and travel books offered in London.

'Versuche über Pflanzen Hybriden' by Gregor Mendel is a paper that marked the foundation of the science of genetics.

Compiled for official British War Office use on the eve of the American War of Independence, this quarto volume bearing the manuscript title ‘The Uniform of the Several Regiments of Foot in His Majesty’s Service’ doubled the high estimate at Christie’s New York (25/20/13.5% buyer’s premium).

Pioneering astronomical works which appeared many centuries before the moon landing sell at auction.

Christie’s highest price for an Old Master this summer came in the stand-alone Masterpieces from a Rothschild Collection sale on July 4.

It may be a well-rehearsed refrain, but the Old Master market is much more subject to vagaries of supply than demand. Almost without fail, when high-quality fresh material is offered, bidders will come. Just getting it in the first place is the hard part.

The marathon 12-hour 'Maharajas & Mughal Magnificence' auction of jewellery and works of art from the Al Thani family held in New York last month was a once-in-a-generation event.

The Hammerhead shark plate shown below is not as colourful as many of the other 432 featured in a generally fine and complete copy of Marcus Elieser Bloch’s Ichthyologie… sold recently, but certainly one of the more eye-catching.

The Antiquities Dealers’ Association (ADA) has said dealers and auctioneers should stand up to “the politicisation of the antiquities trade” in the wake of a row surrounding the sale of a £4m sculpture.

A Pre-Raphaelite drawing once owned by LS Lowry drew lively competition at the latest round of 19th century art sales in London.
