The consumer's only chance / Frank A. Nankivell.
Illustration shows a woman mooring an airship to the chimney on the roof of her home by the light of a full moon; on board the airship are "American Goods Bought in England" that are being smuggled into the U.S. because of high tariffs that make the products too expensive to purchase.
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.
The main types of airship are non-rigid, semi-rigid, and rigid. Non-rigid airships, often called "blimps", rely on internal pressure to maintain the shape of the airship. Semi-rigid airships maintain the envelope shape by internal pressure but have a supporting structure. Rigid airships have an outer structural framework which maintains the shape and carries all structural loads, while the lifting gas is contained in internal gas bags or cells. Rigid airships were first flown by Count Zeppelin and the vast majority of rigid airships built were manufactured by the firm he founded. As a result, all rigid airships are sometimes called zeppelins. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Airships were most commonly used before the 1940s, but their use decreased over time as their capabilities were surpassed by those of aeroplanes.
