Founded in 1939 by Edwin W. Krauter in Chicago, Lettering, Inc. produced its own patented Photo-Ray process of lettering (US Pat 2165861) in which transparent letters made from original alphabets were assembled by hand and then placed in a line (angled or curved if so desired) and then photographed. This "glass setting" process created flawlessly set headlines and, with multiple character forms to choose from, the headline looked authentically lettered.

An early competitor of Photo Lettering, Inc, they employed such notable lettering artists of the time as Oscar Ogg, Ray DaBoll and Ray Baker, among others. At its height in the late 1960s, Lettering, Inc. had as many as 14 franchises operating in the US and Canada and was continually producing new alphabet designs. As the market changed and computer technology evolved, Lettering, Inc. became less of a supplier of type to the ad agencies and became more involved as a supplier of high-end graphics and type to the big Detroit auto makers.

Today, from its Southfield, Michigan office, Lettering, Inc. continues to provide various graphics services to a diverse group of customers.
