ROME (AP).- Italian tax police said Saturday that they had seized works by Van Gogh, Picasso, Cezanne and other giants of art in a crackdown on assets hidden by the disgraced founder of the collapsed dairy company Parmalat. Authorities estimated the 19 masterpieces stashed away in attics and basements were valued at some euro100 million ($150 million). Parma Prosecutor Gerardo Laguardia said that, based on wiretapped phone conversations, officials believed at least one of the paintings hidden by Calisto Tanzi was about to be sold. “We got lucky. We learned that there were negotiations under way to sell one of the paintings” and raid three apartments in the area of Parma, near Parmalat’s headquarters, Laguardia said in an interview on Italy’s Sky TG24 TV. He didn’t identify the painting.
