Major works which John has worked closely on in recent years include J.M.W. Turner’s Giudecca, La Donna della Salute and San Giorgio, Venice (2006; US$35.8M), George Stubbs’ Gimcrack on Newmarket Heath (2011; £22.4M), and John Constable’s The Lock (2012; £22.4M), each representing world record prices. John also handles major private and institutional sales.
While British Painting – a field whose market Christie’s consistently dominates – remains a passion, John works across all schools of European Old Masters. In 2014 John curated the highly successful ‘Art of the Horse’ private selling exhibition which toured to Shanghai and Hong Kong, comprising Asian and Western works of art, from Antiquity to the present day. John leads the Old Master department’s work in Asia.
