Christie's has released the catalogue for its 'Art Contemporain - Vente du Jour' auction, scheduled for October 23 in Paris, putting 141 contemporary works on the block with presale estimates totaling $9.26 million at the low end and $13.64 million at the high end, excluding premiums. The highest-valued lot announced is Josef Albers's Study to Homage to the Square: Earthbound (1958), a square-motif study from the artist's best-known series, estimated at $336,100 to $560,200. The painting has appeared on the secondary market 12 times before, a trading history that suggests sustained collector interest in Albers's Homage works. Further highlights include an Abstract Painting by Gerhard Richter at $336,100 to $560,200, an Untitled work by Alexander Calder estimated at $280,100 to $392,200, and an Untitled Keith Haring at the same range, plus another Albers Homage study. Every lot in the sale carries a published estimate; none are listed with undisclosed figures. No sales in the auction are backed by third-party guarantees, meaning all risk sits with the consignors and the house. The October Paris contemporary season sits in the shadow of Art Basel Paris week, when the city's international collector attention peaks, and the sale's results will be read as a barometer of demand for mid-range postwar and contemporary works ahead of November's New York marquee auctions. The decision to keep every estimate disclosed continues a trend among European salerooms toward full transparency in day sales, where open estimates are meant to attract bidding from dealers and private collectors alike. How the Albers and Richter lots perform against their repeated market appearances will also test whether fatigue has set in for familiar blue-chip names, or whether Paris's October audience is still willing to pay up for proven modernist material.
