I loved The Crown, at least I loved the early episodes before all the Diana nonsense (I'm not a huge fan of the People's Princess!). So it was fun to see this auction exhibition at Bonhams of costumes and props from the series, so clever - even though close-up you'd never mistake them for the real Norman Hartnell etc. I did wonder who is going to bid for a life-size State Coach, looks authentically bone-rattlingly uncomfortable (estimated price £30,000-£50,000); or a Coronation chair with fibreglass Stone of Scone (£10,000-£20,000); the Queen's many ballgowns and Princess Anne's teenage mini-skirt ensemble for the Caernarvon Castle Investiture (£2,000-£3,000); or for smaller budgets perhaps a slightly battered barbecue from Balmoral (£400-£600). Diana's engagement ring? Genuine cubic zirconia (£2,000-£3,000) - or her off-the rail engagement outfit from Harrods (£1,500-£2,000). They said they are expecting lots of interest from America. Where I'm guessing there is perhaps a hazy perception of what's real and what's Netflix. Four floors to browse and it's all free.
