Alma Thomas’s “Red Mums Display” heads to Sotheby’s Contemporary Curated auction on October 7, 2026, with a $500,000–$700,000 estimate. Trader sentiment centers on recent momentum in her secondary market, where major canvases have repeatedly cleared high estimates—most notably “Snoopy Sees Sunrise on Earth,” which fetched $3.78 million against a $1.5 million low in February 2026. Strong demand for her signature colorful abstractions, sustained institutional interest, and limited supply of comparable works on paper or smaller canvases support expectations that the lot could exceed the low end of the range. Key catalysts remain the final hammer price and any late bidding activity in the days leading into the sale.
