Several New York galleries have hit major milestones in recent months, offering lessons from those in charge.
A recent exhibition at Pace Gallery, celebrating its 65th anniversary, showcases the gallery's longevity.
Looking at recent headlines, you could be excused for thinking the traditional dealer model is falling apart.
However, a closer look reveals that New York galleries are thriving, with exhibitions commemorating anniversaries of a decade or more in business.
Smaller galleries, now based in a single city, are also celebrating milestone exhibitions, offering a heartening counterpoint to the challenges facing the sector.
Examples include Pace Gallery's 65th-anniversary group exhibition, on show in Geneva until 7 November.
