Sotheby's will offer a dozen works once owned by the late oil tycoon Armand Hammer at its modern art evening sale in New York this November. The collection carries estimates of $25 million to $37 million, with proceeds benefiting the Armand Hammer Foundation's grants for arts education and institutions.

The top lot is Edgar Degas's circa 1899 painting Trois danseuses (Jupes jaunes), estimated at $10 million to $15 million. Other highlights include Mary Cassatt's 1894–95 Summertime ($7 million–$10 million), Pierre-Auguste Renoir's 1888 Antibes ($2.5 million–$3.5 million), and Camille Pissarro's circa 1883 Paysage à Osny, vue de la ferme ($2 million–$3 million).

The works will be on view at Sotheby's Los Angeles outpost from September 23–25 — a fitting venue, given that Hammer is the namesake of the Hammer Museum in Los Angeles. Jacqueline Wachter, who runs the Sotheby's LA office, said in a release: "Armand Hammer's imprint on Los Angeles is difficult to overstate. He believed that collecting art came with an obligation to share it, a conviction that shaped not only his own museum but decades of gifts to institutions across this city and beyond."

The London gallery Ben Elwes Fine Art has spent the past few years shedding light on the career of Alejandro Mario Yllanes, a Bolivian painter who studied under Diego Rivera and whose work has been overlooked until recently. Yllanes, whose canvases are searing indictments of the Bolivian government's treatment of Indigenous people during the first half of the 20th century, abandoned the majority of his work in an Upper West Side apartment after 1950, roughly a decade before his death.

Since the gallery's first show for Yllanes in fall 2023, its owners, Rachel and Ben Elwes, have sold nearly two dozen works for prices between $400,000 and $1.9 million, the New York Times reports. Among the buyers: the Metropolitan Museum of Art in New York, the Museum of Latin American Art of Buenos Aires, the Bowdoin College Museum of Art in Maine, and the Toledo Museum of Art in Ohio, which acquired Lake Titicaca (1935) in May. Writer Victoria Burnett traces Yllanes's life and art, which art historian Michele Greet describes as a "significant discovery."

The Hammer collection sale in November will test the market for Impressionist works at a moment when marquee evening auctions remain a key barometer for the trade.
