NASHVILLE (AP) — A new, free exhibit at the Tennessee State Library & Archives in Nashville includes photographs taken by James L. Bailey, who became known as "Mr. Conservation."

He crisscrossed the state as a worker for the Tennessee Department of Conservation beginning in 1937. While advocating for conservation, he compiled an extensive collection of photographs.

Additionally, the exhibit includes many photos and postcards collected by the Department of Conservation through the years.

The exhibit highlights the beauty of Reelfoot Lake State Park, Montgomery Bell State Park, the Great Smoky Mountains National Park, the Natchez Trace Parkway and Nashville's Percy Warner Park.
