THE COPYGRAPH

A device for taking many copies of any writing, piece of music, or colored picture made with a common pen. A picture composed of one, two, or even more colors, can be readily transferred by this ingenious process, and 40 or more copies taken. In a writing in one color, 100 copies can be produced.

The Copygraph is just the thing for school teachers, church choirs, business offices, and all others who desire a number of copies of any writing, piece of music, illustration, or lesson to be made out for students. A returned teacher from South Africa used the Copygraph for years in class-work for the students in copying music, illustrations, and lessons. The low price at which it is furnished brings it practically within the reach of all.

By it the intelligent teacher of a class in physiology can readily produce an illustration of the eye, the heart, lungs, or any part of the human mechanism, for use in the recitation room, with but little cost. Or it may be used in printing notices to be circulated. Thus in printing bills.

With this device, a sheet of paper 9 x 12 inches is readily printed. Of course a sheet of a smaller size can be printed just as easily. The arrangement itself is about half an inch larger each way, and weighs nearly three pounds. It is half an inch in depth, and consists of a black tin case, with a cover, in which is a jelly-like mass which receives the impression of the writing or picture. Regular hectograph ink is used. This can be purchased at any book store.

Price of the Copygraph; Postpaid, $2.00.
