Similarly, Wolfgang Beltracchi, a 21st century forger, also bought his frames and supports at antique markets (18).

The infamous Han Van Meegeren (1889–1947), who specialized in forging Vermeer paintings, is known to have scraped the paint off of older paintings to reuse the canvases to yield the illusion of a naturally aged painting substrate (16, 17).In cases where no pigment, filler, or binder anachronisms are identified, the judgment of degradation products arising from natural aging is inconclusive, and radiocarbon dating of the support material is indecisive, dating of the binder in the pictorial layer is indispensable.The idea of identifying modern forgeries based on C dating of the binder was formulated with the advent of AMS (22), but suffered from practical limitation as the study was conducted on 100-mg scale sample material, an unfeasible sampling quantity for artworks. Radiocarbon dating has the potential to answer the question of when an artwork was created, by providing a time frame of the material used.In this study we show that with two microsamples (C age gained on the paint contradicts this as it offers clear evidence for a post-1950 creation.
