The widow of crime boss John Gotti is apparently an artist. And she’s having a show. “A Chelsea gallery is opening a show of Victoria Gotti’s artwork tonight – and a portrait of the late Dapper Don is one of 20 paintings up for grabs. Gotti, who is rarely seen in public, told the Daily News she’s been painting for years. She doesn’t have any professional training, which may be obvious to some art critics. But like Picasso, she apparently does have a blue period.”
