The upcoming November 18 Sotheby’s auction of Vincent van Gogh’s “Châtaigniers en fleurs,” a rare 1890 Auvers landscape unseen publicly for over six decades, drives current market-implied odds favoring a result above the $180 million estimate. Its placement at the head of the $450 million Blaquier-Arrieta Collection sale, combined with strong blue-chip demand and limited private examples from the artist’s final period, fuels trader consensus around record territory. The painting’s late-career context, thick impasto, and fresh Asian and New York previews have built momentum, though a last-minute claim by Fischer family heirs alleging a 1930s sale under Nazi duress introduces uncertainty that could influence final bidding. With the hammer falling in days, any resolution on provenance will shape whether the work clears $225 million or settles closer to the $200 million mark.
