One of London's major antiques dealerships, Sampson and Horne Antiques has announced that they are closing and their entire trading stock will be sold at Bonhams on April 28. The company is closing because one of the founders, Jonathan Horne, is ill and the other partner, Christopher Banks, has decided to scale back. The sale will include British folk art and pottery in a wide range of prices and is set to bring in as much as £1 million.
