It's the Thomas Cole and the Birth of the American Landscape Painting Exhibit.
Cole was a Hudson River Valley painter in the 19th century.
He played a major role in the history of American landscape painting.
Rolling Hills employees said having the exhibit here puts them on the map.
"People think of us just as a library, and when we get things like this, they realize we have lots of fun, and exciting things here. So, we're always happy to have stuff for the patrons to come in and look at, and get them involved in the library," said Robbie Morton from Rolling Hills Library.
The exhibit runs through May 21. It is open Wednesday through Saturday 1 p.m. to 4 p.m., and Sunday 1 p.m. to 5 p.m.
