How Much Is Woman in Black at the Opera Worth?

Dated 1878, the painting belongs to Cassatt’s seminal Paris years and to her signature opera/loge series, which helped define the modern, observational gaze within Impressionism. These works have anchored major exhibitions and scholarship for decades, making them touchstones for institutions and top private collectors. The image’s feminist art-historical resonance—depicting a modern woman navigating public space with agency—continues to amplify its cultural salience and market appeal. Within Cassatt’s output, the opera/loge motif is among the most cited and reproduced, reinforcing its recognition factor and the likelihood of competitive bidding when a comparable example appears. This centrality within the oeuvre warrants a strong premium relative to other themes.

Cassatt’s strongest oils are far scarcer than her pastels and prints, and quality oils command significant premiums. Collectors and museums prize original, unreduced canvases with attractive impasto, legible brushwork, and minimal overpaint. Assuming a stable surface, no material paint loss, and conservation in line with best practice, the medium and presumed condition support the top end of Cassatt’s market. By contrast, Cassatt’s more commonly traded media (etchings, counterproofs) set a lower baseline. As a prime-period oil—particularly in a marquee subject—this work benefits from a medium-related scarcity premium that, all else equal, elevates it above even record-setting works on paper from the same theme.

The opera/loge subject from 1878–79 is among Cassatt’s most coveted themes, instantly recognizable and institutionally validated. Few high-quality oils of this motif remain in private hands; many reside in major museums, constraining supply and heightening competition for any comparable example. The subject’s crossover appeal—to Impressionist collectors, American art buyers, and those focused on women artists—broadens the potential bidder base. Scarcity within a marquee theme typically produces step‑function pricing when quality aligns with demand. This is especially true when a work has strong exhibition/literature history and can anchor a focused collection, connoisseurship narrative, or museum display.

Longstanding inclusion in the Museum of Fine Arts, Boston, signals museum-level quality and art-historical importance. While current institutional ownership reduces near‑term sale likelihood, it positively influences valuation benchmarks: insurers, appraisers, and private‑treaty parties typically ascribe a premium to works validated by major museums. A continuous, reputable provenance chain and extensive bibliography/exhibition history would further enhance value. Conversely, any gaps, deaccession constraints, or export restrictions can affect liquidity. Overall, blue‑chip institutional validation is a value amplifier in replacement scenarios and a confidence signal in hypothetical market pricing.

Cassatt’s auction record—$7.49 million for a closely related late‑1870s loge image on paper—demonstrates deep demand for this subject; important oils have sold in the multi‑million range even for non‑iconic themes. Within the broader Impressionist market, renewed focus on women artists and institutional acquisitions provide supportive tailwinds. Together, these comparables and trends justify low‑to‑mid eight‑figure guidance for a prime 1878 opera/loge oil, with upside if multiple tier‑one bidders emerge. Market selectivity remains real, however: condition, scale, and exhibition history are decisive in pushing results to the top of the range.
