Editor’s picks | Helen Frankenthaler spent her summers from 1958 to 1969 living and working by the sea in Provincetown, Cape Cod. Her 1961 painting Scene: Blue & Yellow shares a palette with others made in the same studio, as well as an airy sense of space — all of which suggests the influence of the location on her work Price on request Private Sales | | This brass figure of Mars is attributed to Hubert Le Sueur, who became sculptor to Henry IV of France in 1608. The god of war is shown in a resting pose, his sword lowered; and the fine detail of the helmet he is wearing, adorned with a lion mask, is probably thanks to the fact that Le Sueur’s father was a master armourer Estimate: €250,000-350,000 12 June, Paris | | The natural world is strongly present in the work of Lynne Drexler, even if it takes on a semi-abstract form. In Solid Summer, from 1994, a gnarled tree trunk stands out against a mosaic of orange, in a whirl of circles and teardrop shapes; and the vivid green foliage around it seems ready to burst from the canvas Estimate: €18,000-25,000 7 June, Paris | | Brazilian furniture designers the Campana brothers teamed up with the artist KAWS in 2019 to produce GANG (Sofa). The brothers had used soft toys in their work before, but here the piled-up plushies are KAWS versions of Bert, Ernie, Big Bird, Elmo and the Cookie Monster from the TV show Sesame Street Estimate: $40,000-60,000 7 June, New York | | Browse Auctions | |
