Four post cards of Davy Crockett Birthplace State Park in Limestone TN. All are pre-1967, when ZIP Codes became mandatory. The top three are published by Haynes Distributing in Roanoke. The top two were printed by Dexter Press. The printer of the third is unknown. Note that the top two also are exactly the same original picture, but the second one has been adjusted to alter the colors (in the printing process, not in the retouching department).
The fourth card, published by American Calendar Company in Greeneville TN, has been retouched, not terribly skillfully, but it gets the job done.
