Located in Marion County, Indiana. According to internet sources, years of operation were 1930-1955. Looks to be late 1930s or early 1940s. No information provided on back. Found in a thrift shop in Fayetteville, Arkansas.
The plate on the vintage Pontiac says ’48. So, it would be a very good guess this was taken in 1948. The vehicle, by all accounts, is a 1941 Pontiac Torpedo and the bumper implores you to “See Beautiful Wonder Cave” in Monteagle, Tennessee. The Indiana plates are 864 369. Here is a very throughout web page describing the county history and cave. No other information on the photograph itself. Found in a thrift shop in Northwest, Arkansas.
