Anybody can operate a new machine that prints 1,500 show cards a day, for it works as easily as a typewriter.
No setting of type is necessary. The device is provided with a row of holes, each representing a letter or figure.
Cards may be printed in two colors at a single operation.
According to the inventor, the device prints signs at a fraction of the cost of ordinary printing, and turns out work of more finished quality than could be done by hand.
