How Much Is The Black Bull Worth?

Overview and object context. The Black Bull (Der schwarze Stier), 1900, oil on canvas, 82 × 82 cm, is an authentic, catalogued Klimt painting in a private collection and currently exhibited at the Leopold Museum in Vienna, with references in the standard literature (Natter; Weidinger/Seiser/Winkler; Novotny/Dobai) [1]. Painted during Klimt’s first summer at the Attersee, it depicts an unusually naturalistic animal subject—distinct from the mature ornamental landscapes and golden-period portraits that dominate the market.

Market environment and top-tier benchmarks. Klimt’s market is among the strongest in pre‑War Modernism. In 2025, Sotheby’s set a new auction record for the artist at $236.4m for a full-length portrait, confirming deep demand at the apex of the category [2]. That same season, two prime landscapes achieved $86.0m and $68.3m, respectively [4]. Earlier, Lady with a Fan realized $108.4m in London (2023) [3]; Insel im Attersee, a period‑adjacent landscape (c.1901–02), made $53.2m in New York (2023) [5]; and Birch Forest (1903) achieved $104.6m in 2022 [6]. These results establish the ceiling for Klimt’s signature subjects.

Positioning of The Black Bull within Klimt’s oeuvre. While an oil-on-canvas by Klimt is intrinsically scarce and highly desirable, The Black Bull’s animal/genre motif is outside the artist’s most competitive categories. Collectors have historically paid a premium for golden-phase portraits and mature ornamental Attersee landscapes, with period, finish, and decorative impact driving the lion’s share of nine-figure outcomes [2][3][4][6]. As a result, this work should price materially below top-tier landscapes like Insel im Attersee ($53.2m) [5] and far below the golden or late masterworks that now occupy the $100m–$236m range [2][3][6]. A meaningful discount to these comparables—reflecting off-core subject appeal and narrower trophy demand—supports the $10–18m range.

Derivation of estimate. We anchor the high side of the bracket to the broader scarcity of Klimt oils and the artist’s elevated market baseline since 2022–2025, while the low end reflects subject-driven constraints and the likelihood that bidding depth will trail that for portraits or ornamental landscapes. The square 82 cm format and Attersee period are positives, as are the robust literature/exhibition references and current display at the Leopold Museum (which strengthens curatorial pedigree and buyer confidence) [1]. A 2003 loan insurance figure (~€5.8m) is historical and not indicative of today’s fair market value [8].

Key sensitivities. This estimate presumes good, unrestored condition with no structural issues, and clear, fully documented provenance—particularly across the 1933–45 period—given the heightened scrutiny in the Austrian/Modern context; unresolved claims can depress or derail transactions (cf. the 2024 Lieser portrait sale cancellation) [7]. Optimal sale timing would be a New York marquee evening auction with third‑party guarantee, which currently commands the deepest bidding in this price band [2][4].

Conclusion. On balance of author, medium, date, literature, and museum exposure—tempered by an off‑core subject—The Black Bull’s fair‑market value synthesizes at $10–18 million today, with upside contingent on pristine condition, fully published provenance, and strong cross‑category competition at sale.
