How Much Is Two Sisters (On the Terrace) Worth?

Valuation conclusion (short): Two Sisters (On the Terrace), 1881 by Pierre‑Auguste Renoir is in the permanent collection of the Art Institute of Chicago (accession 1933.455) and therefore is effectively not on the open market; institutional records and provenance documentation confirm long public ownership and exhibition history [1]. If an authenticated, museum‑quality 1881 Renoir of this subject were to come to market, a reasoned market valuation is provided below based on recent auction comparables, historical top results, and the painting’s documented provenance.

Comparable evidence and market context: Recent sale activity for prime Renoirs and strong late‑19th‑century French figure works shows buyer willingness to pay mid‑ to high single‑figure millions for well‑provenanced examples. For instance, a well‑provenanced late‑1870s/1880s Renoir still life realized c. $8.72M at Sotheby’s London in 2024, and major figure works in similar seasons have approached or exceeded $10M—supporting a multi‑million baseline for top examples [2]. The artist’s historic auction ceiling (Au Moulin de la Galette, 1990, $78.1M) illustrates the upper theoretical limit for a trophy Renoir, though such masterpieces rarely reappear publicly.

Estimate and rationale: Considering date (1881—Renoir’s desirable mature Impressionist period), subject (large double portrait/group figure), and exceptional provenance (Durand‑Ruel → Annie Swan Coburn → Art Institute), a preliminary market range if sold would be approximately USD 15,000,000–60,000,000. The lower band ($15M–$25M) corresponds to smaller scale works, modest exhibition history, or noticeable conservation issues; the mid band ($25M–$45M) to large autograph canvases in sound condition with strong exhibition/publication histories; the upper band ($45M–$60M+) would require pristine condition, exceptional exhibition provenance, and a highly competitive private or evening‑sale bidding environment.

Key qualifiers: This valuation assumes confirmed autograph status, favourable technical condition, and catalogue‑raisonné inclusion or expert attestation. Final value would be determined only after review of the conservation dossier (X‑rays, IR/UV, varnish/relining history), complete provenance documentation, and up‑to‑date catalogue references. The Art Institute’s internal records are likely to contain the technical information that would support a higher valuation [1].

Market route and liquidity: A work with this profile is most realistically sold by private treaty to a major collector or via a controlled auction structure with guarantees and pre‑sale marketing rather than in an open day sale. Institutional ownership makes public sale improbable; deaccession would be rare and legally/ethically sensitive and would materially affect market reception and price outcome.

Next steps to refine the figure: To tighten the estimate to a single figure I recommend providing: high‑resolution images, exact dimensions, the museum conservation report, and catalogue‑raisonné/exhibition citations. With those documents I will prepare a 5‑lot comparable matrix with dollar adjustments for scale, condition and provenance and recommend the optimal sale strategy.
