The world's biggest ever replica baseball bat is 120 feet in height and weights 68,000 pounds (30,844 kg) and was made by bat manufacturer Hillerich Bradsby, from Louisville, Kentucky (USA).
The bat is modeled on the "R43" bat made for Babe Ruth by the same manufacturer. In the spring of 1927, Ruth strode into the factory and asked them to make him some bats. He hit his then record of 60 home runs with the resulting bats that year.
