The martyr / Keppler. - Political cartoon, public domain image

It wasn't really until the 1700s that caricature truly blossomed as a form of political criticism. In the late 1750s, a man named Thomas Townshend began using the techniques employed by earlier engravers and applying them towards a political model. This gave Thompson's cartoons a much greater feeling of propaganda than previous artistic critiques of the time. The intense political climate of the period, and often accusatory nature of most political cartoons forced many artists to use pseudonyms in order to avoid accusations of libel. Other artists took it a step farther, and left their cartoons completely unsigned, foregoing any credit they may have received. Political higher-ups were notoriously touchy about their reputations and were not afraid to make examples of offenders. Puck was the first successful humor magazine in the United States of colorful cartoons, caricatures and political satire of the issues of the day. It was published from 1871 until 1918.

Udo J. Keppler, known from 1894 as Joseph Keppler Jr., was an American political cartoonist, publisher, and Native American advocate. The son of cartoonist Joseph Keppler (1838–1894), who founded Puck magazine, the younger Keppler also contributed cartoons, and became co-owner of the magazine after his father's death, when he changed his name to Joseph Keppler. He was also a collector of Native American artifacts, and was adopted by the Seneca Nation, where he became an honorary chief and given the name Gyantwaka.
