The Diane A. Nixon drawings collection arrives at Sotheby’s on 4 February 2026 with unusual gravity. This is not a routine Old Masters sale. It is the public unveiling of a collection shaped in near total anonymity and sustained by decades of scholarly rigor.
Comprising around 130 lots, the sale represents one of the most academically coherent assemblies of Old Master drawings to reach the market in over a decade. Its importance lies not in spectacle, but in judgment.
