A Norman Rockwell painting which recently sold for more than $1 million (£667,000) has been reported missing.

New York Police Department officials are seeking help from the public after a private collector alerted them to his missing masterpiece, titled Sport, which vanished from a warehouse in Queens.

The painting was once owned by model Fred Hildebrandt, who is depicted as an angler in a boat in the famous piece.

It was sold at a Sotheby's auction in May (13).
