How Much Is The Sisters Worth?

The Sisters, dated 1869, sits in an important developmental period for Morisot as she moved toward Impressionist practice. Works of this period that demonstrate her characteristic handling of light, intimate domestic subject matter and nuanced female portraiture are highly regarded by both scholars and collectors. If the painting is a fully finished, large‑format portrait group that is well executed and documented, it carries high art‑historical value because it exemplifies Morisot’s early mastery and subject focus. This significance increases institutional interest and collector competition, which supports higher market valuations, particularly when corroborated by exhibition history and catalogue entries.

Secure provenance to prominent Parisian dealers (Bernheim‑Jeune and Durand‑Ruel) and to the Carstairs collection, culminating in a bequest to the National Gallery of Art, materially reduces attribution and authenticity risk and raises buyer confidence. Museum ownership is a strong positive signal in the market; it typically increases a work’s salability and realized price if offered. Conversely, absence of documented provenance or gaps in ownership history would significantly reduce marketability. Exhibition or catalogue citations would further enhance value by placing the work in scholarly context.

Technical condition is one of the single most value‑sensitive factors. Original paint surface and stable support with minimal restoration sustain full market value. Major issues — pervasive retouching, extensive relining, varnish discoloration or structural instability — can reduce a work’s desirability and the number of competitive bidders, often lowering realizations by multiples. A contemporary, detailed conservator’s report and imaging (X‑ray, infrared) are essential to confirm state and to quantify any restoration discounts that would be applied in a sale estimate.

Comparable auction results for museum‑quality Morisot oils anchor the estimate. The artist’s auction high and several mid‑to‑high results for portraits/interiors establish an achievable upper range under ideal sale conditions. However, Morisot’s market is segmented: day‑sale offerings and small studies fetch substantially less than evening‑sale, well‑provenanced canvases. The painting’s scale, subject and documented comparability to recent seven‑figure lots determine where it sits within that segmentation, making comparables critical to pricing strategy.

Placement in an evening sale at a marquee auction house (New York or London) during Impressionist/19th‑century sales weeks can materially elevate final realizations due to higher bidder attendance and greater publicity. By contrast, day‑sale placement, off‑market private sale, or sale during weak market windows typically reduces competitive pressure and final price. Timing relative to major exhibitions, anniversaries, or renewed scholarly focus on Morisot can also amplify demand and price, so strategic timing and marketing are important value drivers.
