This souvenir bell is from the 1982 World's Fair in Knoxville, Tennessee. This bell has a small plastic disc that covers the logo and the words "The 1982 World's Fair Knoxville TN May-October." The back side of the bell is of the same metal as the rest. I believe that the bell is made of brass.
This bell measures approximately 4 inches tall. It is in excellent condition, with no damage that I see.
