Klimt painting: doubts about a work would emerge from an expert

There would be doubts about 'Portrait of a Lady', the painting by Gustav Klimt accidentally found in recent days at the Ricci Oddi modern art gallery in Piacenza 22 years after the theft occurred in the same place in 1997. From the Prosecutor of the Republic of Piacenza some leaked rumors - unofficial - about a first appraisal carried out in the last hours by one of the consultants appointed by the judiciary to establish the actual authenticity of the work.
The whole affair, since the day the priceless canvas was found on a shelf in the garden inside a garbage bag, is surrounded by an impenetrable reserve maintained by the investigators. The painting is currently in a secret location, in custody, to be subjected to the necessary expert reports.
Three experts have been assigned the task, and one of these, the first to have seen the canvas, would have raised the first doubts, even if at the moment it is not known whether it is technical and physical elements on the materials, or artistic related to the painting and the technique of its author.
