How Much Is Portrait of a Kleptomaniac Worth?

Estimated fair-market value (hypothetical): $30–50 million. Portrait of a Kleptomaniac (Le Monomane du vol) is one of the most important images from Géricault’s late “portraits of the insane.” The painting is held by the Museum of Fine Arts, Ghent (MSK Gent; inv. 1908‑F), acquired in 1908 after a Paris sale and subsequently kept in the museum’s collection [1]. As a museum-held masterpiece, it is not a market object; however, an informed valuation can be derived by extrapolating from the artist’s auction record, the work’s exceptional status within the oeuvre, and cross-artist benchmarks for 19th‑century museum-caliber portraits.

Method and anchors. Géricault’s painting auction record—Portrait d’Alfred et Élisabeth Dedreux—made €9,025,000 ($11.6m) at Christie’s Paris in 2009 [2]. Adjusted for inflation, that implies a ~mid‑to‑high‑teens million baseline today for a major but non-iconic portrait by the artist. Portrait of a Kleptomaniac commands a significant premium over that baseline: it is a cornerstone of Géricault’s late output and an emblem of early 19th‑century engagement with psychiatry, reproduced and discussed across art-historical literature. Cross‑artist comparables show what the market pays for truly canonical 19th‑century portraiture when supply appears: Manet’s Self‑Portrait with Palette fetched $33.2m in 2011 (≈$45m today), illustrating the headroom for blue‑chip masters at auction.

Market signals for demand. While top-tier Géricault oils almost never trade, recent public sales of authenticated works on paper demonstrate robust, international demand: a high‑quality watercolor brought €496,650 at Drouot in 2026, and other sheets have performed solidly in Paris since 2024 [3][4]. These results corroborate depth of interest for vetted material and support the premise that a masterpiece‑level oil—if ever available—would attract trophy‑level bidders across regions.

Rationale for the $30–50m bracket. The range is built upward from the inflation‑adjusted 2009 record, then calibrated for the painting’s art‑historical centrality, iconicity within a celebrated series, and extreme scarcity of autograph Géricault oils outside institutions. The lower bound (~$30m) reflects a conservative premium to the adjusted record for an undeniably major subject; the upper bound (~$50m) aligns with pricing observed for museum‑caliber 19th‑century portraits by top French masters when rare opportunities arise, and anticipates competition in a cross‑category trophy market.

Practical considerations. The estimate assumes an unencumbered, fully exportable picture in strong condition with unambiguous attribution and literature. In reality, the work is museum‑held, and any deaccession/export constraints would shape venue and buyer pool. Within those assumptions, however, a $30–50 million outcome is well supported by the artist’s standing, the painting’s significance, and recent market behavior for best‑of‑category historical works [1][2][3][4].
