If It Came To Market
Easel Index SPECULATIVE VALUATIONS — WORKS CURRENTLY HELD IN MUSEUMS, PRIVATE COLLECTIONS OR WITH UNCERTAIN STATUS
The Concert, c. 1664 — Isabella Stewart Gardner Museum, Boston. Stolen March 18, 1990.
Stolen alongside 12 other works in history's largest unsolved art theft. A Vermeer of this calibre — a three-figure interior at a harpsichord — would command a record by an order of magnitude beyond any prior Vermeer sale. Title status makes legitimate sale extraordinarily complex. A hypothetical sale would likely exceed every prior Vermeer by a factor of three or more. The closest modern comparable: Leonardo's Salvator Mundi at $450.3m, Christie's New York, November 2017.

PRIVATE · STATUS UNCERTAIN
Benefits Supervisor Sleeping, 1995 — believed held by Roman Abramovich collection
Last sold by Christie's New York in 2008 for $33.6m — then the most expensive work by a living artist. Subsequently acquired by Roman Abramovich. UK and EU sanction-related asset freezes create legal ambiguity around title and ability to transact. Were it to emerge at auction in 2026 free of all encumbrance, the secondary Freud market has strengthened significantly — Leigh Bowery canvases of comparable scale now clear £30m routinely. The work represents an extraordinary trapped asset.

DISPUTED ATTRIBUTION
La Bella Principessa, c. 1496 — private Swiss collection
Attribution confirmed by Professor Martin Kemp (Oxford) and supported by fingerprint analysis; contested by a minority of scholars. Currently held in private Swiss hands and valued as disputed. Were attribution definitively established through scientific consensus, value would likely rival Salvator Mundi. Current discount reflects attribution uncertainty alone, not demand for confirmed Leonardo — where institutional and private appetite is essentially unlimited at any price.
Nativity with St. Francis and St. Lawrence, c. 1600 — Oratory of San Lorenzo, Palermo, stolen October 1969
Removed from its altarpiece in a single night. Multiple investigations have linked its movement to the Sicilian Mafia; occasional credible sightings have been reported and dismissed. Were it to emerge legally and in good condition — a near-impossibility given its history — the sale would be the cultural event of a generation. Market value assumes an entirely hypothetical best-case scenario: clean title, good condition, legitimate consignment.
Untitled (Bacchus) triptych, 2006 — Cy Twombly Foundation, Rome. Never separated. Never offered.
Individual Bacchus panels of comparable scale have cleared $35m at auction. The Foundation holds the complete triptych in its original configuration. A consignment to a major New York evening sale would anchor an entire sale and drive secondary market activity across the Twombly estate simultaneously. The Foundation has shown no indication of deaccessioning any major work to date.
