Tennessee Centennial Exposition Souvenir

I got permission to hunt a farm field a couple of weeks ago and found what I thought was a dog tag. The farmer has an annual Dove Shoot in this field and there were a lot of shotgun shells. So I figured this was a tag from one of the hunters dog. I cleaned the tag last night and was surprised to find a Tennessee Centennial Exposition tag. The Exposition was held in Nashville during the month of May 1897. After I researched online the building on the tag appears to be the Children's Building. The only building remaining in Centennial Park today is the Parthenon on West End Avenue across the street from Vanderbilt University.
