BIG MAP OF OHIO AT WORLDS FAIR

Ohio’s geography is explained to World’s Fair visitors by a mechanical map of pressed wood and glass, twelve feet square, provided with 1,302 indexed push buttons. To find any city, river, or point of historical interest, the user pushes a button and one or more squares are instantly illuminated.

    You know, I think it would be easier to find a spot on the map than it would be to find its button.
