The front of the post card has an image of the entrance and dance floor at Dunbar Cave in Clarksville, TN. On the back is a caption that reads, “Modernly lighted gravel walks wind through 4 miles of underground caverns. Numerous streams are well bridged. Air-conditioned by Mother Nature at a temperature of 56 degrees Fahrenheit. Orchestras of radio fame play here weekly during the summer season.”
