An armchair spectator conveyer-guide

Visitors to the General Motors “Futurama” at the 1939 New York World´s Fair, an extensive scale model purporting to depict the America of tomorrow, were transported through the exhibit on a specially designed and constructed conveyer consisting of a continuous train of moving chairs almost one-third of a mile long. Loudspeakers provided each individual spectator with a running account of the changing scene throughout the tour.
