Sonja Knips Auction History

1897/98–1950: In the collection of the sitter, Sonja Knips (Vienna) [1].

1950–present: Österreichische Galerie Belvedere, Vienna (inv. no. 4403); purchased directly from Sonja Knips [1][2].

Sonja Knips occupies a pivotal place in Gustav Klimt’s portraiture. Painted in 1897/1898 and first shown at the Vienna Secession’s Second Exhibition, the square-format canvas marks an early, decisive move into the artist’s modern Secessionist idiom [2]. Because the picture remained with the sitter until 1950—when it was purchased by the Österreichische Galerie Belvedere—it has no public auction history and has been continuously preserved in a major museum collection (inv. no. 4403) [1][2]. As museums seldom deaccession, the work has not participated in price discovery and instead functions as a benchmark of quality and art-historical importance within institutional narratives.

Collectors seeking proximity to this landmark portrait often pursue related drawings. The Vienna auction house im Kinsky has sold several studies connected to the painting; for example, on 5 December 2017 a Study for the portrait of Sonja Knips achieved €102,400 including fees, with further Knips studies offered in 2018–2019 [4]. These results reflect demand for early Secession-period material, while underscoring that the finished museum painting itself remains outside the market.

The broader Klimt market underscores sustained global appetite for top-tier works. Recent high-profile results include Lady with a Fan (1917) at Sotheby’s London on 27 June 2023 for £85.3 million with fees [5]; Birch Forest (1903) at Christie’s New York on 9 November 2022 for $104.5 million with fees [6]; Portrait of Adele Bloch-Bauer II (1912) at Christie’s New York on 8 November 2006 for $87,936,000 [7]; and Bauerngarten (Flower Garden) (1907) at Sotheby’s London on 1 March 2017 for £48 million with fees [8]. Against this backdrop, Sonja Knips serves as a museum-grade reference point for Klimt’s emergence as a society portraitist—central to his oeuvre and scholarship—even as its secure public ownership means it does not directly set auction comparables [1][2].
