It happens sometimes when an exhibition is prepared, when selecting works, thinking about them, investigating their lives, restoring them if it is the case, sometimes surprises arise. There is a memorable case among the exhibitions held in Valencia. This is the case of the exhibition that took place in the MuVIM from April 27 to July 16, 2006 "Valencian painting in the Ermitage collection. Centuries XVI-XVII". The well-known Russian museum ceded works of Valencian painters of the Renaissance that it hoards in its collections, and on the occasion of the preparatory works of the exhibition in the MuVIM, which were carried out by the curators of the Valencian museum, it was discovered that some of the works donated for the exposition was false (or let's say that the authorship had been attributed in the wrong way).
