Products of Printing
Printing has been aptly designated “the art preservative of all arts.” The product of the printer’s trade is so well known as to require little comment. Books, periodicals, newspapers, commercial forms, advertising literature, and other products of the press form a competent part of the business and social structure of all civilized nations, and are integral parts of the daily life of practically every individual. Hardly any other field of human activity has a product so universally used.
