Some 60 exhibitors gather in the purpose-built marquee in the grounds of the West Sussex mansion (as seen recently in Ridley Scott’s Napoleon movie), their stands selling both antiques and art. Look out for Tom Rooth’s hand-drawn honeycomb ceramics, Gladwell & Patterson’s display of Peter Symonds’ landscapes, art deco furniture and accessories from Jeroen Markies, and a collection of Francis Bacon prints from Ottocento. Plus much, much more, of course: go delve.
