M.A. Rosko heads to Mound City Hall, the new home of the city's historical society to investigate the Tonka Trucks on display -- once a major source of employment in the city.
Before Tonka Trucks were folded into Hasbro, they were a huge asset in the city and carried the name Mound Metal Works. M.A. uncovers more of the history behind the toy that's still plenty popular today, and how much those old models could be worth.
