DescriptionThe Pan American Louisville and Nashville.JPG
Postcard photo of the Louisville and Nashville train "The Pan-American".
Date
Not mailed. The train first entered service in 1921 and was streamlined in 1940. The photo is of the original, heavyweight train. Because the card mentions the train having a radio, I believe this card dates from the mid 1920s to 1930s. The train stopped running in 1971 after Amtrak assumed most railroads' passenger service.
There are no copyright marks on the card as can be seen by both views.
