The Hocking Hills is a term given to the area in southeastern Ohio located predominately in Hocking County. Millions of tourists visit the valley each year to experience the primary feature of the Hocking Hills: the beautiful and historic cave system that stands today as it has for eons. From 1900 to 1950, the caves were a popular subject for postcard images, and town and country residents who lived and worked in this area were captured on vintage postcards. Residents created their own entertainment, and Main Street parades, the county fair, holidays, patriotic events, and family gatherings were celebrated and recorded with penny postcards.
