Twelve dining chairs that were part of Glasgow's renowned Miss Cranston's Tea Rooms, and thought lost, have emerged at an auctioneers in England and are expected to sell for £20,000.

Kate Cranston's Tea Rooms, in Buchanan Street, opened in 1897, with the interiors and furniture designed by Glasgow artist George Walton and friezes by Charles Rennie Mackintosh.

The armchairs were thought to have been lost and dispersed many years ago. But they were being used by the descendants of the family, who bought them from the tea rooms when it closed.

They will be sold at in Dorset on September 26.
