Two Swedish-American buyers are suing London’s Alison Jacques gallery, accusing breach of contract over the sale of three works by the Swedish-born artist Monica Sjöö, whose estate Jacques represents.

The estate and the gallery say that Marie St. Germain, the adviser to Yoed and Natasha Anise, misrepresented the couple ahead of the purchase; they also claim that they believe the Anises would not be promising stewards of the artist’s works, the Art Newspaper (TAN) reports. The Anises, who paid £264,000 (about $358,000) for three paintings from the 1990s, split their time between Stockholm and Austin, Texas, and operate a tech company.
