Artist Picasso's famous "Dream" painting was poked with a hole the size of silver dollar by Las Vegas casino magnate Steve Wynn. He had accidentally elbowed the multimillion dollar canvas.

Wynn had just sold the painting for $139 million to another collector when the incident occurred while he was showing the painting to friends at his Las Vegas office.

Director and screenwriter Nora Ephron, who witnessed the incident wrote about it in her blog (www.huffingtonpost.com).

"At that moment, his elbow crashed backward right through the canvas. There was a terrible noise," Ephron wrote. She mentioned that Wynn has retinitis pigmentosa, an eye disease that affects peripheral vision.

She wrote, "Smack in the middle ... was a black hole the size of a silver dollar. 'Oh sh*t,' he said. 'Look what I've done. Thank goodness it was me.'"

Wynn's office confirmed the story and said the buyer was released from the sale agreement and Wynn has decided to repair and keep the painting.

Wynn, is a millionaire casino developer and art collector, credited to reinvigorating the once-seedy Las Vegas Strip.
