A show of work by Richard Prince that opened this week at London’s Serpentine Gallery is being held “in collaboration” with the luxury goods company Louis Vuitton, marking yet another crossover between the art and fashion worlds. Prince is one of a stable of contemporary artists, including Takashi Murakami, Julie Verhoeven, Stephen Sprouse and Robert Wilson, who have been brought on board by the French fashion house. Like Murakami, Prince has designed bags for Vuitton; but unlike Murakami, whose current show at the Brooklyn Museum of Art (until July 13) features a Vuitton shop, Prince handbags will not be for sale at the Serpentine. There will be a limited edition of “Jamais” bags on sale in the Vuitton London shops during the show, at £9,000 each.

Two of London’s most respected dealers in 18th-century English furniture, Jeremy and Hotspur, are closing shop and selling all their stock together at Christie’s in November. John Hill of Jeremy explains that their gallery lease was coming up for renewal and “it was time to have fewer responsibilities and to give a chance to the younger generation”. The departure of Hotspur, established in 1924, and Jeremy, established in 1946, reduces the number of quality antique furniture dealers in London at a time when the market is suffering. The very best pieces are making huge prices – a Chippendale cabinet sold at Christie’s for more than £2.7m this month – but the mid-market is extremely flat.
