A painting stolen by the Nazis that was spotted in an Argentinian estate agent's advert has vanished, a prosecutor says following a raid on the home. Portrait of a Lady by Giuseppe Ghislandi was featured hanging above a sofa inside a property near Buenos Aires, which was being sold by the daughter of a senior Nazi who fled Germany after World War Two. A police raid on the house this week, however, turned up no painting - but two weapons were seized, federal prosecutor Carlos Martínez told local media. Mr. Martínez stated they were treating it as an alleged cover-up of smuggling, Argentinian daily Clarin reported. The furnishings were rearranged and the picture was missing from the wall when they raided the property. Evidence suggested 'the painting was removed shortly afterwards or after the media reports about it appeared'. The investigation revealed that the painting was part of the collection of Amsterdam art dealer Jacques Goudstikker, much of which was forcibly sold by the Nazis after his death. For more than 80 years, the location of late-baroque Italian portraitist Giuseppe Ghislandi's painting had been unknown until its recent appearance and subsequent disappearance.
