The Macklowe Gallery from New York specialises in 20th century decorative arts, notably Art Nouveau, Tiffany works and jewellery.
Among the works it is taking to the Winter Show is this 3ft 10in x 2ft 6in (1.2m x 76cm) stained glass Wisteria Tiffany window priced at $575,000 (left). The view it depicts is possibly from Laurelton Hall, Tiffany’s country estate.
