The Procuress

A forged version of Dirck van Baburen's Procuress — the picture-within-a-picture that hangs on the rear wall of Vermeer's The Concert and Lady Seated at a Virginal. Presented in 1960 and held by the Courtauld Institute since, the work was confirmed in 2011 to be a 20th-century fake by bakelite analysis and is generally attributed to Han van Meegeren.
