MOSS' PROCESS NO. 67 PARK PLACE NEW YORK [Illustration] RELIEF PLATES IN HARD TYPE METAL, FOR PRINTING ALL KINDS OF PICTORIAL ILLUSTRATIONS IN BOOKS, NEWSPAPERS, AND CATALOGUES. These plates are an excellent substitute for woodcuts, being used in precisely the same way, giving equally good results for much less money. ELECTROTYPES AND STEREOTYPES are made from them in the usual manner. We offer special advantages to MANUFACTURERS AND INVENTORS, as our mechanical work is of the best quality and rapidly executed. Our plates are used satisfactorily in the SCIENTIFIC AMERICAN and the SCIENTIFIC AMERICAN SUPPLEMENT, and by Manufacturers and Publishers in all parts of the country. "COPY" We work direct only from Prints or properly prepared Pen and Ink Drawings. Any other copy may be furnished, such as Photographs, Pencil Sketches, or the articles themselves, in which cases we have drawings made in the best manner by our own trained draughtsmen. Photographs, taken in the ordinary way, are suitable, and they may be of any size. We make the plates larger or smaller, as desired. We are glad to have customers prepare their own Pen Drawings, and append one or two, DIRECTIONS TO ARTISTS: The most important requisite in Drawings for our use is that every line shall be _perfectly black._ The paper or drawing board must be _white_ and _smooth_. For fine work drawings should be made double the scale of the plate desired. Carefully observing these main points, the artist has the utmost freedom in his choice of styles of drawing. For further information and fine samples of our work, send stamp for current number of our illustrated _Quarterly Circular_. * * * * *
