A few years ago, during a storage room clean out at the University of São Paulo (Biblioteca do Conjunto das Químicas), several items were discarded, including apparently modern worthless large-scale reproductions of paintings by famous painters. A member of staff retrieved these reproductions from the litter bin, one of which was carefully inspected and non-destructively analyzed by spectroscopic techniques (Raman and XRF). The results showed that instead of being a modern reproduction of the gouache "Clinique de Sannois" (Maurice Utrillo, 1923), it was hand-painted probably between the late 1940s and early 1950s using the Jacomet process. This technique was developed by the French printer Daniel Jacomet in the 1920s, who made authorized reproductions of works of art by some of the most celebrated painters of the time
