Half-tone Engraving: How to Obtain a Patent, Copp & Co. Patent Attorneys, Washington, D.C.

This halftone engraving by James Henry Moser represents a fascinating intersection of art and commerce in late 19th or early 20th century America. Moser, an American artist active between the 1870s and 1913, is known primarily as a watercolorist and etcher who captured landscapes and scenes of the American West and Washington, D.C. This piece, however, showcases the era's burgeoning print advertising industry, serving as promotional material for Copp & Co., a patent attorney firm in the nation's capital.

The halftone process—a revolutionary photomechanical printing technique developed in the 1880s—allowed for the reproduction of continuous-tone images through patterns of tiny dots. This technological innovation transformed commercial printing and advertising, making illustrated promotional materials widely accessible and affordable. Moser's involvement in creating this advertisement demonstrates how fine artists often worked in commercial contexts during this period. The subject matter—explaining the patent process—reflects the rapid industrialization and innovation of the Gilded Age, when securing intellectual property protection became increasingly important for inventors and entrepreneurs. While this engraving may seem purely functional, it represents an important moment when artistic skill merged with emerging reproduction technologies to serve the expanding needs of American business.
