The art piece was an 800-pound ball-peen hammer made of metal with a long redwood handle. The hammer measures 21 feet long and the head is 6 feet tall.

The piece, valued at $15,000, was loaned by the artist about a year ago to the Healdsburg Community Center and was not insured. It vanished from the lawn sometime Friday night or Saturday morning.
