Alma Thomas’s market has shown consistent upward momentum, fueled by institutional recognition and strong results for comparable large-scale acrylic canvases from the 1970s. “Red Mums Display,” offered at Sotheby’s Contemporary Curated sale on October 7 with a $500,000–$700,000 estimate, sits in a segment where recent works have frequently exceeded mid-range expectations. Traders are weighing the artist’s thin supply, rising auction records near $4 million, and ongoing traveling exhibitions such as the Smithsonian’s “Composing Color” against the risk of softer performance in a curated rather than evening sale. The outcome hinges on whether the lot cleared or surpassed its high estimate amid broader demand for Washington Color School abstraction.
