A particular highlight in June 2021 was the auction of the “Sander Collection,” whose origins trace back to the internationally renowned photographer August Sander. After a thrilling bidding battle, Franz Wilhelm Seiwert’s painting “Wandbild für einen Fotografen” soared past expectations, reaching 1,225,000 euros (estimate: 400,000–600,000) and simultaneously setting a new world record for the artist.  The iconic 1925 work is now on display at the Art Institute of Chicago. With a sales value exceeding 200 percent of estimates, the auction underscored the collection’s extraordinary resonance on the market.
