A Natural Color Card by Walter M. Cline Co., Chattanooga, Tenn.
The description states:
THE LOWER TUNNEL on the Transmountain Highway U.S. 441 through the Great Smoky Mountains National Park. To the left may be seen the Chimney Tops which dominate the view for several miles along this highway. This is one of two tunnels on this highway which were built in order to avoid steep grades as the highway climbs to the top of the main range of the Great Smoky Mountains.
The picture is dated on the card as taken in 1955.
