How Much Is Composition with Red, Blue and Grey Worth?

Valuation conclusion: Using published auction comparables and the confirmed 2014 Sotheby’s result as the primary market datum, I estimate a market range of $30,000,000–$50,000,000 for Piet Mondrian’s Composition with Red, Blue and Grey (1927) when the work is authenticated, in good condition, and accompanied by the provenance and exhibition history published with the Sotheby’s lot [1].

Anchor and comparables: The anchor is the Sotheby’s London evening‑sale result (23 June 2014) for the exact painting (price realized £15,202,500 ≈ USD $25.9M), which the house catalogued with catalogue‑raisonné and exhibition references; that sale is the single best direct market datum for this object and establishes a firm baseline [1]. Top‑end market evidence from closely related, canonical late‑1920s/1930 Mondrians — notably the Christie’s May 2015 Composition No. III (realized ≈ USD $50.565M) and Sotheby’s record 2022 sale (≈ USD $51M) — demonstrates that museum‑quality, larger or more historically pivotal canvases can trade substantially higher [2][3]. More recent single‑owner offerings (e.g., Christie’s Riggio sale, May 2025) continue to show demand in the mid‑to‑high tens of millions for prime Neoplastic canvases [4].

How the range was derived: I begin with the 2014 realized price as the primary datum and account for two effects: (A) time‑value adjustments and general positive repricing for premium Mondrians since 2014, and (B) the observed dispersion between smaller/mid‑scale studio canvases and larger, canonical museum pieces. Inflation‑ and market‑adjusting the 2014 result produces an approximate mid‑30s million USD reference point; the low end of my range ($30M) reflects a conservative market re‑pricing for a small/medium 1927 composition in the current market, while the high end ($50M) represents an outcome where the work (1) benefits from superior condition, (2) is offered in a prime evening sale or single‑owner context that generates institutional interest, and (3) faces active competition from trophy buyers [1][2][3].

Key sensitivities & next steps: The single greatest determinants that would push the estimate up or down are condition and any restoration history, confirmed catalogue‑raisonné/authentication status, depth and clarity of provenance and exhibition history, and the chosen sales route (evening sale with guarantees vs. timed or private sale). Recommended next steps to firm value: obtain a formal condition report and technical imaging (X‑ray, IRR, pigment analysis); confirm catalogue‑raisonné entry and loan/exhibition records; request provenance documentation and ownership/title checks; and solicit formal pre‑sale estimates or guarantees from major houses. With those items verified, this preliminary range can be narrowed to a firm pre‑sale estimate or a guaranteed offer.

Confidence statement: This is a reasoned market estimate based on published auction outcomes and observable market movement through 2025. It is not a replacement for a physical inspection, authentication report, and formal auction house underwriting, all of which materially affect realized price.
