He began to tell the story of the Picasso’s provenance. As he talked, he had his back to the picture. He was wearing jeans and a golf shirt...without realizing it, he backed up a step or two as he talked. “So then I made a gesture with my right hand,” Wynn said, “and my right elbow hit the picture. It punctured the picture.” There was a distinct ripping sound.
Another rich guy was going to pay "a hundred and thirty-nine million dollars for it, the highest known price ever paid for a work of art" but the deal was off. Then, "Later that week, Wynn’s wife, Elaine, took the painting to New York in Wynn’s jet, where she and 'Le Rêve' were met by an armored truck."
That's quite an expensive mistake.
