Alma Thomas’s “Red Mums Display,” estimated at $500,000–$700,000, heads to Sotheby’s Contemporary Curated sale on October 7, 2026. Recent secondary-market results for the Washington Color School pioneer show sustained momentum, with multiple lots exceeding estimates and one major canvas reaching $3.78 million earlier this year. Growing institutional interest, including new publications and traveling exhibitions focused on her mosaic-like abstractions drawn from nature, supports collector demand. Traders will watch presale interest and any last-minute comparables, as her prices have historically responded quickly to fresh auction data and critical attention in the weeks before major sales.
