Made by L.C. Smith & Corona Typewriter Inc., Syracuse, New York. Marketed by the Corona Company with the slogan "A gift to help little fingers guide eager young minds". The company equipped normal portable typewriters, in this case the model "Sterling", for the small surcharge of 2.49 US dollars with the "Animal Keyboard". U.S. design patent no. 100245 was granted to Myrtle R. Keller in 1936 for this ornamental innovation. All the animal illustrations are by Byron Glee Newton, a well-known American artist.
