Cartoonists and caricature artists make their point through a variety of methods, including the exaggeration of traits or characteristics and the use of symbols to represent organizations, concepts, and ideas. Comic strips often use American postal icons, such as mailboxes and letter carriers, to help make a scene easily recognizable as an American street, city, or home. In some cases, a postal employee has become a regular feature in a comic strip. Cartoonists and caricature artists continue to put their pens to work using postal themes both for humor as well as to make serious points.
