When such drawings cannot be furnished us, we can produce them from photographs, pencil sketches, or designs of any kind accompanied with proper instructions. Photographs taken in the usual way, and of any convenient size, we can use. CHANGE OF SIZE.--Wood-cut prints of the coarser kind may often be reduced to half their lineal dimensions, while others will admit of very little reduction, and some of none at all. Most lithographic and steel-plate prints will admit of no reduction. Very fine prints of any kind may be _enlarged_ moderately without detriment. Any prints which cannot be satisfactorily reduced or enlarged may be _redrawn_ and thus brought to any desired size. In all cases of reduction and enlargement, the relative proportions remain unchanged. PROOFS.--Whenever desired, we will furnish tintype proofs of the drawings made by us, for approval or correction, before engraving. A printed proof is furnished with each plate. TIME.--We cannot usually engage to fill an order for a single plate in less than from three to six days; larger orders will require longer time. ESTIMATES will be promptly furnished when desired. That these may be definite and correct, the copy to be used--whether print, photograph, sketch, or drawing--should always be submitted for our examination, together with a distinct statement of the size of plate wanted, and of any other details to be observed. TERMS.--To insure attention, all orders must be accompanied by an advance of half the price charged, the balance to be paid on delivery. ELECTROTYPING AND PRINTING.--We have recently added to our establishment excellent facilities for making electrotypes, and also three power presses specially fitted for printing plates of all sizes in the finest manner. ARTIFICIAL LIGHT.--We have just introduced this most important facility, which enables us to prosecute our work _in cloudy weather_, and to push forward hurried orders _in the night_. REFERENCES.--Our plates are now used by the principal publishers in this city, and by most of the leading houses in every State in the Union. OUR GENERAL CIRCULAR contains a few specimens of the various kinds of our work, and will be sent on receipt of stamp. We have just prepared five special circulars, as follows: No. 1. Portraits and Figures. No. 2. Buildings and Landscapes. No. 3. Machinery and Apparatus. No. 4. Maps, Autographs, and Ornamental Lettering. No. 5. Reproductions from Wood-Cuts, Steel-Plate Prints, and Lithographs. These will be furnished at _ten cents_ each. * * * * * ADVERTISEMENTS.
