CHICAGO – On May 4, Hindman Auctions will present Joan Mitchell’s (American, 1926-1992) Untitled, 1989 as the centerpiece of its Post War and Contemporary Art auction, where it will be offered with an estimate of $500,000-$700,000. Executed during the later years of her career, this work is an outstanding example of her shift towards lush and transcendent painting. The softer strokes and sense of restraint in Untitled, 1989 contrast Mitchell’s (American, 1925-1992) slashing paint handling in earlier work, while still illustrating her singular vision and timeless approach. Absentee and Internet live bidding will be available through LiveAuctioneers.
