DENVER -- The Denver Zoo is working with the Denver Art Museum in its effort to restore a 367-year-old painting.
The museum used a large animal X-ray machine, typically used on polar bears and tigers, to analyze the nearly 7-feet tall painting called the “Virgin of Valvanera."
The images will then be used to come up with a detailed plan for its restoration.
"Virgin of Valvanera" was finished around the year 1700 by Mexican artist Cristobal De Villalpando. It's one of only three of his paintings here in the U.S.
