Typeface

In 1842, the first U.S. design patent, was issued for typefaces and borders patented by George Bruce of New York City (No. D1). This new form of patent was authorized by Act of Congress on 29 Aug 1842. In its text, Bruce wrote "It is difficult to find much in Printer's Types that is new in design if we regard only their characteristic lines, but if we look at the ways in which the figures are varied while the characteristic lines are retained, we find the same variety that would be expected in the portraits of a person painted by many different artists in different positions" and "...these Types are different from all others in their size, proportions, details and impressive effects, containing peculiarities by which they are distinguished..."«[Image: Stock art of flourishes, not part of patent; The available Patent Office record of this patent does not show samples of the patented designs.]
