In this episode, Antiques Roadshow comes from the colourful surrounds of Morden Hall Park in south London, where big value finds include a rare Cartier driver’s watch, a tiny painting by a German impressionist and a plate designed by Pablo Picasso. Jewellery specialist Joanna Hardy is dazzled by a diamond-studded replica of a brooch originally designed for Wallis Simpson, the Duchess of Windsor, while glass specialist Andy McConnell covets three early 18th-century pieces bought for just a few pence. Alexandra Gill admires a painting by renowned Cuban artist René Portocarrero and hears how it was given as a gift by Cuban leader Fidel Castro. Hilary Kay delivers a show-stopping valuation when she appraises a remarkable self-portrait by John Lennon and Yoko Ono, done shortly after their wedding and famous ‘bed-in’ of 1969.
