“Photo-Graver” Makes Cuts Over Wire in Ten Minutes

WHAT is certain to be one of the most revolutionary machines introduced in the printing industry was recently exhibited in New York City. Called the “Photo-Graver”, the machine is capable of turning out a half tone engraving in approximately ten minutes, without using either chemical or photographic processes.
