REVIEW 2025
THE YEAR 2025 AT KOLLER
2025 exceeded all expectations at Koller.
While the press predicted a downturn in the auction market, our auctions were vibrant, full of surprises and highly successful. Rediscovered works and extraordinary stories made the year one of the most exciting in recent times.
