Park Mammoth Resort: Slave Cave, Underground Railway chrome ~ Undated Tichnor Brothers Lusterchrome postcard K-13101 is small-sized and typical of the issues of the 1950s to the 1970s. This particular example is near mint. The odd pattern was caused by scanning a halftone and does not exist on the actual card which is sharp and clear.

Located just outside Park City in Kentucky's Mammoth Cave area, Park Mammoth Resort has been a popular destination for travelers from around the United States, since 1964. The Civil War Era Train replica was removed several years ago.
