Lego Battery-Powered Vehicle Frame
Trains weren’t the only vehicle Lego was motorizing. In 1972 you could also get this motorized framework for building a myriad of different vehicles powered by a battery-filled controller connected by a wire. The set included standard wheels, as well two caterpillar treads for building construction vehicles or tanks—even though Lego never encourages kids to build vehicles of war. 40.50 Danish Krone, or U.S. $5.80.
