Lalanne mirrors owned by Yves Saint Laurent and a classic Diane Arbus photo: our pick of the April auctions

Major auction houses are preparing for a series of high-profile sales in April, headlined by a suite of fifteen gilt-bronze mirrors by Claude Lalanne. Originally commissioned for the Paris apartment of fashion icon Yves Saint Laurent and Pierre Bergé, the mirrors are expected to fetch between $10m and $15m at Sotheby’s. Other notable lots include a rare Diane Arbus photograph from the collection of Lily Tomlin and Jane Wagner, a pastoral landscape by Russian artist Konstantin Somov, and a centuries-old drawing based on Albrecht Dürer’s famous rhinoceros woodcut.
