London gallery Archeus / Post-Modern has organized a by-appointment presentation titled "Bridget Riley: Sixties. The Complete Black and White Graphic Works." The exhibition brings together a rare, complete suite of seven prints on paper and seven companion works on Plexiglas, known as *Fragments*, all created by the English Op Art pioneer in the early-to-mid 1960s.
James Stourton, former chairman of Sotheby's UK, has written a book titled "Rogues and Scholars" that chronicles the rise of London's art market after World War II. The article highlights key moments such as Sotheby's 1958 sale of the Goldschmidt collection of Impressionist art, which transformed auctions into glamorous evening events, and the introduction of the buyer's premium in 1975, which Stourton calls "the Big Bang of the art world." It also profiles influential dealers and galleries like Marlborough Gallery, Robert Fraser, Christopher Gibbs, and Robin Symes who shaped global tastes from London.
