FILE - This Aug. 20, 2016 file photo shows Cedar Grove, the home of artist Thomas Cole, considered the founder of the famous genre of American landscape painting known as the Hudson River School, in Catskill, N.Y. Not only did Cole paint the lush mountain landscapes that inspired the Hudson River School art movement of the 19th century, he also painted on the walls of his home. Pretty decorative patterns on the walls in the parlor of his Catskill home had been buried beneath layers of paint for more than a century before they were discovered a few years ago.

Not only did Cole paint the lush mountain landscapes that inspired the Hudson River School art movement of the 19th century, he also painted pretty decorative patterns on the walls in the parlor of his Catskill home that had been buried beneath layers of paint for more than a century before they were discovered a few years ago. Now curators have painstakingly revealed the stylized depictions of drapery and fabric so they can be displayed when the Thomas Cole National Historic Site opens for the season in May 2017.
