The post in grant and farm
A book on the history of the postal service, written by James Wilson Hyde and published in London in 1894, aimed at a general historical readership. Its one picture is a black-and-white royal coat of arms with a crown, supporters of a lion and a unicorn, and the motto 'Dieu et mon droit' on a scroll, which a designer could take as a bold, symmetrical heraldic emblem.
