Jennifer Gilbert selling art worth millions to aid Detroit nonprofit

Detroit philanthropist and entrepreneur Jennifer Gilbert is selling major artworks from her personal collection at Sotheby’s this spring, with proceeds going to Lumana, a new Detroit-based arts nonprofit she founded. The collection will be offered across multiple sales, including The Now and Contemporary Evening Auction and Contemporary Day Auction in May, followed by Important Design in June. Highlights include Kenneth Noland’s 1958 painting “Circle” (estimated $4–6 million, a record for the artist) and Joan Mitchell’s 1976 painting “Loom II” (estimated $5–7 million).
